COUNTDOWN TO MDS LEGENDARY 2026 – ISSUE FOUR

This is it. Two weeks to go.

This edition marks the 40th anniversary of the MDS Legendary. Four decades of runners crossing the Sahara under their own power. As we move through March, I’m sharing a short series of weekly articles to help sharpen your preparation. This is the fourth of four.

By now, the nerves are real. Anticipation is building. And yes, stress might be creeping in too. That’s normal. You’re about to take on one of the toughest endurance races on the planet. But here’s the truth: the hard work is already done.

Now, the focus shifts.

Ease Back to Move Forward

It’s tempting to squeeze in one last long run. Don’t.

At this stage, there’s nothing to gain and everything to lose. Fatigue and injury are the only likely outcomes. Instead, keep sessions short and purposeful. Stay loose. Stay sharp. This is taper time. Think of it as recharging your battery so you arrive on the start line fresh, not drained.

Prepare for the Heat

If you can, use these final days to adapt to the heat. It doesn’t need to be perfect, but every little bit helps.

Hot yoga, saunas, hot baths, even treadmill sessions with extra layers can all make a difference. If you have access to a heat chamber, even better. The Sahara is unforgiving, and any adaptation you build now will pay off when it matters most.

Plan Everything, Then Simplify

Now is the time to get meticulous.

Lay everything out. Build a spreadsheet if that helps. Go item by item through your kit. Ask yourself what you truly need.

Weight matters. Every gram counts when it’s on your back for multiple days. Strip out the luxuries. Be ruthless. The goal is to go as light as possible without compromising safety or performance.

The same applies to food. Check your calories. Repack if needed. Remove excess packaging. Make sure what you carry is efficient, practical, and something you can actually eat under stress.

Get the Admin Right

Details matter here.

Medical certificates must be correct and meet all race requirements, especially your ECG. Don’t assume, double-check.

Photo by Ian Corless

Your passport needs to be valid. It sounds obvious, but it catches people out every year. Confirm your travel documents, bookings, and transfers. Know your plan from departure to arrival.

The goal is simple: remove every possible source of stress before you leave.

Travel Smart

Wear your race kit when you travel. That includes your shoes and gaiters.

Your race pack should go as carry-on, with all essential gear inside. The only items that should go in checked luggage are those that have to, like a knife or trekking poles.

If checked luggage gets delayed, you’ll still be able to race. That’s the mindset.

Protect Your Health

This part might feel extreme, but it’s important.

Avoid unnecessary contact with others. A cold or virus now could undo months of work. Skip handshakes, hugs, and shared food or drinks. A simple “Namaste” with hands together works just fine.

You’ve come too far to risk it.

Be Smart Before the Start

When you arrive in Morocco, keep things simple.

Avoid salads or anything that might carry risk. Stick to well-cooked, straightforward meals. This isn’t the time to experiment with local cuisine.

Bring your own food for travel and the days before the race. Remember, you’re self-sufficient even before the start. Having familiar food and drink helps you stay relaxed and in control.

Use the Bivouac to Your Advantage

Before admin, your luggage stays with you in the bivouac. Use this.

Bring spares. Extra layers. Small options that allow you to adjust based on real conditions. The desert can surprise you, and this is your chance to fine-tune your setup before committing fully.

Be Ready

Have a clear plan for admin. Know what’s required. Be organized.

Then shift your focus forward.

Stage 1 is coming.

Trust the Process

You’ve done the training. You’ve made the sacrifices. You’ve earned your place on that start line.

Now it’s about arriving calm, prepared, and ready to embrace what’s ahead.

Because this isn’t just a race.

It’s a journey. An experience that will stay with you long after the dust has settled.

Take a breath. Stay focused. And get ready for the adventure of a lifetime.

COUNTDOWN TO MDS LEGENDARY 2026 – ISSUE THREE

Marathon des Sables: What a Week in the Desert Really Looks Like

The Marathon des Sables has always been legendary. In 2026, it becomes something even more special.

This edition marks the 40th anniversary of the race. Four decades of runners crossing the Sahara under their own power. Forty years of stories, struggle, and unforgettable moments. To honour that history, the 2026 race will be longer, tougher, and designed to celebrate everything the event has become.

As we move through March, I’m sharing a short series of weekly articles to help sharpen your preparation. This is the third of four. The goal is simple: remove uncertainty. 

When you arrive in the desert, you should know what to expect.

For many runners, especially first-timers, the unknowns can feel overwhelming. What happens when you arrive in Morocco? 

  • How does the bivouac work? 
  • What does a typical day look like? 
  • And how do the logistics of such a remote race actually function?

Let’s walk through it together.

The Evolution of the Race

The Marathon des Sables has changed over the years, and many of those changes focus on reducing environmental impact.

Past participants will notice significant differences. Charter planes have been removed. More transport now happens overland. The race increasingly relies on local staff and local produce. Media presence has been reduced. A storage centre in Morocco limits the need for shipping equipment every year. Transport trucks have been reduced, and power-saving measures are everywhere, including solar energy.

Water management has also evolved. In the past, runners received 1.5-litre bottles. Today, the race distributes 5-litre bottles, dramatically reducing plastic use during the event.

Behind the scenes is a large support structure dedicated to safety.

• Around 120 medical staff, known as the Orange Jackets, monitor runner safety 24 hours a day.

• The Blue Jackets focus on runner relations. They are present in the bivouac, on the course, and at checkpoints. If you have a question or concern, they are your first point of contact.

Out on the course, SSV vehicles provide rapid access across the route and carry medical professionals for immediate response. In addition, there are 12 support 4×4 vehicles and a unique system of 40 camel patrol teams. These local teams monitor specific zones and report any issues quickly.

Add to that 20 medical patrol staff on the course and another 25 blue and orange jacket team members, and you begin to see how carefully the race is supported despite its remote setting.

Arriving in Morocco

Your journey begins in Ouarzazate, the meeting point for the race.

Plan to arrive at least one day early. This gives you time to settle in and avoids unnecessary stress before the adventure begins. Hotels are your responsibility to book.

The organisation provides free transfers from Marrakech to Ouarzazate, usually departing from the airport and a designated hotel. Always check official timings before travelling.

Photo by Ian Corless

On Day 1, buses depart from Ouarzazate for the first bivouac. The journey takes roughly six hours across spectacular desert landscapes. A lunch pack is provided, but it’s wise to bring extra snacks and drinks.

When you arrive at the bivouac, you’ll be assigned a tent number. Remember you are self-sufficient in regard to food, water is provided. For the moment, you still have access to your luggage. The following day, after administrative checks, you will deposit that luggage and begin the self-sufficient part of the race.

From this point forward, the desert becomes your home.

Life in the Bivouac

Bivouac life is simple. Very simple.

There are no showers and no power. You live under traditional desert tents with seven other runners. It can feel crowded when everyone is organising gear, so respect each other’s space and keep things tidy.

There are a few practical rules that quickly become important:

• Toilets are installed throughout the bivouac and at checkpoints.

• Some toilets are designated women-only or mixed-use, and it’s important to respect those arrangements.

• Biodegradable hygiene bags are provided and waste is separated into organic and sanitary bins.

©iancorless

Phones are strongly discouraged in camp. The bivouac is meant to be a place for rest, conversation, and disconnection. If you need to make an emergency call, move away from camp out of respect for others.

There is also an IP phone available for emergency calls, costing €2 per minute.

Another change from previous years is the removal of the email message system. This reinforces the race’s self-sufficient spirit and saves thousands of sheets of paper that were previously used to print messages.

Instead, runners can use Emotion Boxes to record short video messages that are sent to loved ones. You need to designate before the race who these messages will be sent to.

At the centre of camp sits the Info Tent, where Blue Jackets are always present. This is where you:

• collect your daily water

• ask questions

• check rankings

• access medical support if needed

Additional facilities include women’s changing cabins and sanitary products available both in the bivouac and at checkpoints.

A few other important bivouac rules:

• Never light a fire within 50 cm of tents

• Do not walk barefoot

• Drop empty water bottles at designated recycling points

• On bivouac move days, return containers to the Info Tent

It may sound strict, but these rules keep the camp safe, clean, and functioning smoothly.

The First Administrative Day

Administrative day begins at 9:00 AM.

This is when everything becomes official.

©iancorless

You will go through administrative, technical, and medical checks, while the MDS shop opens nearby. At the shop you can purchase WAA apparel, fire bricks and any other last-minute things you may have forgotten or need.

Each runner receives one 5-litre bottle of mineral water, which must last until the first checkpoint of the race.

Before heading to the checks, prepare the required documents:

• Passport

• Completed technical control form

• Medical certificate

• Resting electrocardiogram (ECG)

During the admin process you will:

1. Deposit your luggage (it will later be returned to you in Ouarzazate).

2. Present your documents and mandatory equipment.

3. Have your race pack weighed.

4. Undergo medical verification.

5. Receive your GPS beacon.

6. Submit your technical control form and receive two race bibs.

If you need to discard a personal item listed on your form later, you must inform the organisation or risk a penalty.

Later in the day:

4:30 PM – Stage briefing

6:00 PM – 40th anniversary photo session

The race is now very real.

A Typical Day in the Desert

Every stage day follows a similar rhythm. Wake up will typically be around 0400 to 0500.

Breakfast is self-sufficient, using the food you’ve carried with you.

Stage tart times vary, but be prepared and ready for 05:30. If temperatures are high, the start may move earlier. Plan for at least 90 minutes of preparation before the start.

Thirty minutes before the stage begins, you must be ready. The race starts on time and no one is held back.

Out on the course, each checkpoint typically between 8-10km’s provides:

• water distribution

• medical presence

• toilets and hygiene supplies

At the finish line, you receive a 5-litre bottle of water, which must last until the first checkpoint the following day. To clarify, you need to drink, cook dinner, wash (if you can spare the water), make breakfast and fill bottles ready to last to CP1 all from the 5ltr bottle.

Each evening the Info Tent and medical clinic are open.

Safety in the Desert

Despite the race’s self-sufficient nature, medical support is extensive. Assistance is available before, during, and after every stage. However, runners are expected to understand basic foot care, which is essential during multi-day desert racing.

For more serious problems, the Dokever medical team takes over.

If you must withdraw from the race, you must notify the organisation. In emergencies, medical evacuation will occur. For non-emergency withdrawals, transport will be arranged back to Ouarzazate, but hotel and food costs will be your responsibility.

At night during a stage, headlamps are mandatory.

Navigation and Desert Conditions

The course is marked clearly and all checkpoints are mandatory. Cutting across the course is forbidden.

Compass headings in the road book are provided as guidance if visibility becomes poor. Know how to use a compass and take a bearing!

Sandstorms

If a sandstorm arrives:

• protect your eyes – you need good glasses and ideally goggles

• cover your nose and mouth typically with a Buff or similar

• stay close to other runners 

Photo by Ian Corless

If visibility drops, stop moving and immediately remove compass and take a bearing for the direction of travel. When conditions improve you can move again relying on the compass bearing to ensure you are going in the correct direction.

If you stray from the course, the organisation will receive an alert from your GPS beacon and locate you.

If You Become Lost

It is highly unlikely that you become lost at MDS, however, it is possible to stray of course and feel disorientated. If you cannot see course markings for ten minutes:

1. Stop and assess your position.

2. Climb a small rise if possible to scan the horizon.

3. Backtrack for up to ten minutes if necessary.

Remember, you have a tracker, so, MDS organisation will know where you are and will be able to find you – do not panic.

As a last resort, activate the SOS function on your GPS beacon.

Distress signals can also be made using whistle blasts or torch flashes at night

To alert SOS with a whistle, the internationally recognized distress signal is three short, sharp blasts, followed by a pause, and then repeated. While the full Morse code for SOS is three short, three long, and three short blasts, the simplified “three blasts” method is more commonly used in disaster preparedness to call for help.

To alert SOS with a torch, flash the light in a repeating pattern of three short flashes, three long flashes, and three short flashes.

Medical Requirements

All runners declare medical information during registration.

During race checks, you must present:

• an original medical certificate

• a resting ECG

Photo by Ian Corless

Failure to provide these documents results in disqualification, though emergency testing may be available on site for a €200 fee.

Medical staff specialise in sports and tropical medicine and operate throughout the race.

They also have the authority to withdraw any runner deemed medically unfit to continue.

The Stages

The 2026 race covers approximately 270 kilometres +/- across the Sahara. Total elevation gain will be around 2500m +/-

Confirmed distances will be in the road book, anticipate the following +/- km’s.

Stages include:

• Stage 1: 37 km

• Stage 2: 41 km

• Stage 3: 29 km

• Stage 4: 100 km (You have two days to complete this stage.)

• Stage 5: 42 km

• Stage 6: 21 km

Photo by Ian Corless

To complete the race properly, runners must carry enough food to provide at least 14,000 calories. Remember, this is the minimum, you may well need more than this, so, balance calorie requirement and weight carefully.

The runner is self-sufficient and must carry ALL they need for the whole race, water the only exception.

After Each Stage

Once you reach the bivouac again, recovery begins immediately. You will receive a 5ltr water allocation which must last to CP1 the next day. Stage 4 an exception due to the rest day where extra water will be allocated.

Photo by Ian Corless

Start with a recovery drink before preparing food. 

Important – take off your shoes and socks right away. Let your feet breathe and inspect them carefully while you are waiting for water to boil or, you are waiting for a meal to hydrate.

Eat a meal within 1-hour of finishing the stage.

Changing into clean or warmer clothing can make a huge difference. It allows running gear to dry and gives a mental reset for the next day. However, you also need to balance weight – keep ‘extras’ to an absolute minimum.

Sleep and rest is another priority. A sleeping mat helps enormously for rest, relaxation and sleep comfort. Your sleeping bag must be light but warm enough for desert nights. We are all different, so know what you need.

Be meticulous with your gear. Eight runners share each tent, and it can quickly become cluttered. Keep your bag packed and store items immediately after using them. Desert winds or sudden sandstorms can easily carry equipment away, especially lightweight items like sleeping mats.

Photo by Ian Corless

A Buff around your neck is invaluable. It lets you cover your nose, mouth, eyes, and ears quickly when conditions change.

Many tent groups also create a simple cooking area using stones and small branches for fire. Often the first runner back begins preparing the cooking area for everyone else.

Over time, these small routines become part of the experience.

And the bivouac itself becomes something special.

You will share the tent with people from all over the world. You will go through highs and lows together. Some moments will be difficult. Others unforgettable.

Many runners say the friendships formed here last a lifetime.

That is the spirit of Marathon des Sables.

After the Finish on Stage 6

Cross the finish line of the final stage and you will receive your medal, water allocation, and a packed lunch.

Photo by Ian Corless

Then you board a bus back to Ouarzazate. Buses leave as soon as they are full, so, no need to hang around and wait for ages.

The bus will take you to your specific hotel and your luggage will be waiting at your hotel.

What comes next is simple but glorious:

  • a shower…
  • then another shower…
  • and maybe one more.
  • Clean clothes. 
  • A real bed. 
  • A proper meal.

The following day is free to relax and explore. Remember the MDS shop! Later in the afternoon there is a dinner, awards ceremony, and celebration party.

After that, the journey home begins.

But the memories of the desert tend to stay with you far longer.

MDS THE ULTIMATE GUIDE

The MARATHON DES SABLES is a unique adventure of 250km’s spread over 6-stages of self-sufficiency, shared by thousands of enthusiasts, in 2026 it celebrates 40-years. In 2017, another format, HMDS was born with 70 to 120km distances, spread over 3-stages and 4-days.

Since 2024 there has been a significant changes for the MDS brand. The ‘HMDS’ format while still following the same protocols and format has now dropped the ‘half’ title and moving forward, events will be called MDS 120 Jordan, MDS 120 Morocco, MDS 120 Cappadocia and so on.

To differentiate the full distance race of 250km’s, Marathon des Sables will now be known at MDS Legendary, reflecting the legendary status of this iconic event and its long history as a pioneer of the stage racing and multi-day format.

All the races are now owned by the same team and while many may be familiar with the format and protocols for the shorter distance races, MDS Legendary since 2024 has had some significant changes. 

Camp life and the desert, it is special. ©iancorless
A 360 experience ©iancorless

Since 2024, MDS has expanded beyond its roots with MDS 120, the exploratory MDS TREK, the demanding MDS RAID, the mind-bending MDS Crazy Loops. and MDS ULTRA – Morocco. And the inspiring, MDS HANDI. Each one a new take on the same promise, to push the limits of what a runner can handle.

MDS EVENTS

  • MDS The Legendary
  • MDS 120 Atlantic Coast Morocco
  • MDS RAID Namibia
  • MDS 120 Cappadocia
  • MDS Crazy Loops – currently 2 locations in France.
  • MDS 120 Fuerteventura
  • MDS 120 Morocco
  • MDS Trek Morocco
  • MDS Handi Morocco
  • MDS 120 Jordan
  • MDS 120 Peru*
  • MDS ULTRA – Morocco

* Every 3-years.

WHAT IS MDS?

MDS is a self-sufficient race taking place over 3 to 6-stages. 

Bivouac life.

MDS Legendary is the iconic 6-stage race (over 7-days) with a distance of 250km (+/-) based on the route, terrain and difficulty. There are no options available on distance and participants are self-sufficient for the entire race, the only exception is the provision of water and a shared tent (bivouac) with 7 other participants. An example of 2024 distances:

  • Stage 1 : 31.1 km
  • Stage 2 : 40.8 km
  • Stage 3 : 85.3 km (over 2 days)
  • Stage 4 : 43.1 km
  • Stage 5 : 31.4 km
  • Stage 6 : 21.1 km

MDS 120 events start at 70, 100 and 120km for the shorter race format, depending on the race destination, there are 2 or 3 distances available. To clarify, this is not 2 or 3 different races, but the same race with the option to choose what distance you run or walk. As an example, the route is divided into 3 stages (4-days), to be completed at your own pace: walking or running. 

  • –    70 km
  • –    100 km
  • –    120 km

Here is a breakdown of each stage:

  • –    Stage 1: 25km – 30km
  • –    Stage 2: 20, 40 or 60km
  • –    Stage 3: 25km – 30km

The choice of the format is made at the registration. However, you can adjust it until the time of MDS.

MDS RAID follows a similar format to MDS 120.

MDS TREK is not self-sufficient and while similar to other MDS events, the format is much more a holiday experience, ideal for first timers or those who are looking for an active travel/ relax experience. Read more HERE.

THE MDS FORMAT

MDS The Legendary and MDS 120 events follow a similar format, however, there are key differences:

MDS The Legendary is a 10-day experience

MDS 120 a 7-day experience

In both scenarios you arrange travel to the relevant destination, arriving with adequate time to meet the MDS team at a designated meeting point and time. This may mean you need to arrive one day in advance to ensure you are able to meet the schedule as stipulated. From here, the MDS team then transport you to the start of the race. 

For MDS Legendary this will be a flight to Marrakech and free transport is offered to Ouarzazate.

For MDS 120 / TREK / RAID and ULTRA events, the meeting point will be a specific airport for transfer to hotel. 

MDS The Legendary use classic Nomad tents that hold 8-participants. By contrast, MDS 120 events use individual tents organised in cells of 6. TREK has upgraded tents, RAID combines solo tents and a star night, MDS ULTRA will be hotels except when racing.

Post-race you will be transported to a hotel and an awards ceremony and gala dinner will take place.

EVENTS

MDS LEGENDARY the iconic 6-stage, 250km race celebrating 40-years in 2026.

MDS 120 (used to be HMDS) this is 3-stages over 4-days with distance options of 70/ 100 or 120km.

MDS TREK this is similar to the MDS 120 format, however, there is no self-sufficiency, more comfortable accommodation and additional facilities, an excellent introduction to the MDS.

MDS RAID an event for more experienced athletes that is undertaken in teams of two, over approximately 90-120km’s, typically, two distance options are provided. The format is similar to MDS 120 with 3-stages over 4-days. One night will be undertaken under the stars with no bivouac.

MDS ULTRA new for 2025, a 100-mile or 100km single stage race with a 40-hour cut off.

MDS CRAZY LOOPS three new events for 2025 undertaken in ski resorts, the format is to run as many loops as possible in 24-hours. The loops will be typically, 3-5km’s in length.

MDS HANDI an inspiring inclusive event to provide wheel chair athletes an opportunity to participate with team members.

THE RACE CONCEPT

You carry all you need for the race. ©iancorless

Both race formats, MDS Legendary, MDS 120, MDS RAID and MDS ULTRA require participants to be self-sufficient for the whole race.

What does this mean?

Quite simply, you must wear and carry all you need for your race experience with the exception of the tent / bivouac. MDS ULTRA will not require a bivouac or same kit requirements as MDS Legendary, Raid or 120.

It may sound daunting but it is not, it’s actually quite simple. You need to address the following points:

  • What you wear.
  • Equipment you need to participate.
  • Sleeping.
  • Food.
  • Cooking equipment. (You can purchase fuel blocks in bivouac)
  • Water.

WHAT TO WEAR

  • Hat to protect from the sun with optional neck protection.
  • Shirt (short or long sleeve) with adequate protection from the sun.
  • Shorts, skort or similar.
  • Socks.
  • Shoes with appropriate protection and durability for a desert environment with a gaiter (typically sewn on) to keep sand out of the shoe.

WAA is a partner for MDS have specific equipment for desert/ stage-racing.

Because you have entered a MDS event, there is no need to buy new apparel and shoes. Quite simply, if you have items that work, are comfortable, cause no problems or irritation, there is no need to change them. If it aint broke, don’t break it. Shoes always create a huge debate and please find what works for you. If you ask on any forum, you will get countless recommendations but none of those recommendations are specific to you and your needs. Read an article HERE and HERE.

EQUIPMENT

MDS runner ©iancorless

Always remember that with MDS events you are either wearing or carrying everything you need for the race duration. Therefore, it is imperative that you purchase the lightest options available (based on budget) and you keep luxuries to a minimum. 

Keep it simple!

MDS specify ‘mandatory’ equipment for participation as specified below:

The Road Book provides all the info about the race and route ©iancorless
  • A pack with enough capacity to carry all your equipment, food and water – eg: WAA Ultra Bag 20L
  • Water carrying capacity of 1.5L minimum.
  • Sleeping bag read HERE
  • Headlamp (which must be turned on after dark) + 1 complete set of spare batteries or battery. Make sure it has a ‘red’ mode for night.
  • 10 safety pins
  • Lighter
  • A whistle
  • Metal blade knife
  • Skin antiseptic
  • Signaling mirror
  • Survival blanket
  • Soup cubes (2 per day) to help the rehydration
  • Tube of sunscreen 
  • 100 / 200 euros in cash 
  • Passport or identity card (depending of the destination) 
  • Official MDS medical certificate completed by a doctor (form available 3 months before the race).
  • Road book
Each runner has a tracker for safety ©iancorless

What else do you need?

  • A sleeping mat is highly recommended to protect from the ground, insulate and provide comfort.
  • A jacket is highly recommended (lightweight down) for cold morning and chilly nights. Many products exist. An excellent combination item is offered by PHD but it does come at a price – HERE.
  • Poles are for many 4-wheel drive in stage races, Leki are highly recommended.
  • Stove – if you plan to have hot water, you will need a cooking system like those provided by Esbit. Please note, you cannot use any gas stoves in the desert, you must use fire bricks which you can purchase at bivouac.
  • Pot – if you are using a stove, you will need a pot/ mug
  • Spoon with long handle for eating. Such as a Spork.
  • Buff or neck roll.
  • Sunglasses are essential and think about protection in sand storms, goggles may be required.
  • Spare socks and Injinji are highly recommended.
  • Flip flops or similar. Many use the weight free slippers from hotels, however, they rarely withstand the desert.
  • Watch / GPX
  • Personal items: Tooth brush, toothpaste, hand gel, wipes, toilet paper, ear plugs, blind fold etc.
  • Emergency – Things can happen during a race, so, be prepared with some essential items such as needle and thread, superglue, zip ties, monkey tape etc. If something rips or breaks, you need to repair it.

Luxuries

MDS is and should be simple in format. Remember, you must carry everything, so, keep luxuries to a minimum. Many consider a small MP3 player, look for something small, light and with great battery.

Phones are an essential part of our daily lives, do yourself a favour and leave it at home. The liberation is extremely rewarding. Please note, phones are allowed, however, it is prohibited to telephone on the bivouac or on the course. If you want to make a phone call, you will have to move away from these places so as not to disturb anyone.

SLEEPING

A sleeping bag is mandatory, so, there is no discussion here. The combined weight of your food is the heaviest and bulkiest item, however, a sleeping bag is next. These days there are many options available and quite simply you want the lightest possible, with the smallest packing size with required warmth at a price that you can afford. Not all sleeping bags are the same, so, consider this. Down is the best filling as it is the lightest, warmest and packs small. However, ‘fill power’ is a key element of down, fill power tells you how much volume a 30-gram, or one-ounce, sample of down will take up. So, the higher the fill power, the warmer the bag will be for less weight, because that one ounce of down has larger down clusters that provide more loft and have the ability to trap more heat. These bags will be more expensive.

Brands to look at: Nordisk, Seat to Summit, Rab, PHD, Western Mountaineering, Wilsa, Lightwave and so on.

Note here, that you will also probably be taking a down jacket for warmth. This can be used as extra warmth and insulation in a sleeping bag. So, it is possible to think about getting a lighter, less warm bag and supplementing warmth with a jacket.

UK brand PHD has come up with the perfect solution with an Ultra Jacket and Desert Race Half Bag but is does come at a price. However, it is comparable with the costs of jacket and bag by Nordisk.

Sleeping mat is highly recommended. When you are not running or walking, you are sitting or lying down, comfort is key. Two options exist, inflatable or not. Inflatable provides the greatest comfort but with poor admin does have the risk of puncture. Sea to Summit provide excellent inflatable options with low weight and pack size. Exped have excellent closed-cell foam.

FOOD

Plan food in day bags ©iancorless

The MDS 120 events (TREK not included) are self-sufficient adventures. You  need to bring your own food and carry it in your bag for the duration of the race.There is a requirement that you must have 2000 calories minimum per day. Please remember that from 2024, catering is not provided at MDS The Legendary and therefore you must have enough food and calories before the race starts.

Food is the heaviest item you will carry and is essential. Don’t skimp on food. Lay food out per day addressing key items:

  • Breakfast (be careful they are not too sweet)
  • Snacks while running (bars, nuts, dried meat etc)
  • Post-run recovery (usually liquid form is ideal)
  • Lunch if applicable (this could be another meal such as cous cous)
  • Dinner (dehydrated meal)
  • Evening snack (a bar)

Where possible, repackage food to make them smaller and lighter. However, make sure you keep nutritional information for the admin day. Pack food in day bags, that way it is easy to know what you have and importantly, you don’t take food you need for the next days. Keep doing this and you will be short of food at the end of the week.

Be organised with all your items ©iancorless

Food is personal and you must find out what works for you. Remember taste chances when fatigued and in hot environments, often, sweet becomes less palatable with a preference for savoury. Dehydrated meals will often be used for key meals such as breakfast and dinner, some hydrate well with just warm water, others need hot water. So, if you are not taking a stove, test this. Basecamp food is a good website that shows what options exist. After many tests, highly recommended products are Firepot, Lyo, Tentmeals and Adventure Menu. Personally speaking, Firepot produce the tastiest meals I have tried.

Make sure you add some treats to spice up your palette.

A food list for MDS The Legendary could look like this:

  • Dehydrated Meals x6 672g
  • Dried Mango 93g x 4 372g
  • Porridge 59g x 7 413g
  • Coffee 1g x 10 10g
  • Peanut Butter 33g x 5 165g
  • Honey 21g x 8 168g
  • Mini Salami 10g x 10 100g

  • Sesame Bites 27g x 6 162g
  • Dried Banana Block 270g
  • Mixed Nuts 200g x 2 400g
  • Macademia Nuts Bag 153g
  • Cranberries Bag 175g
  • Pitta Wraps 296g

Total Weight 3550g

WATER

Water is provided at checkpoints by MDS staff ©iancorless

Water provision, particularly at MDS The Legendary and MDS 120 has changed. In past editions, water was rationed and provided at key checkpoints in bottles, typically, 10km’s apart. 

In 2024, the new organisation changed this and arguably, water is now available, as required whilst racing. It is poured from jugs by MDS staff.

 In addition, intermediate water stations are added when deemed necessary to ensure competitor safety. 

Iced water – amazing. ©iancorless

At key checkpoints, iced water is supplied and poured by MDS staff on the heads and neck to aid cooling.

Post-race, each runner is provided with a 5L bottle of water, this is used for evening cooking, breakfast and up to CP1 the next day. If you wish to wash or freshen up, this comes from the same water ration. So, prioritise food and drinking before washing.

THOUGHTS AND CONSIDERATION

MDS is available for all, be that racing snake or someone who is looking for the adventure of a lifetime. So, keep that in mind. A top runner will have his or her pack at the absolute minimum weight and will look to survive the week racing as fast as possible. They will spend the week hungry. You, for example, may wish to carry a little more weight and have some comfort during the week. Just don’t carry to much extra weight!

The pack you wear is a crucial item that not only must fit everything you need, but it must also be comfortable and allow easy access to drink. There is no one-stop solution here. We are all different sizes and have different body shapes, so, make sure you try options.Also remember, at the beginning of the race, your pack can be around 8kg, this adds extra pressure on the shoulders, so, make sure you have enough padding and comfort. Many packs now come with waist belts and this, for many, is a great solution not only for extra storage but weight distribution. WAA have the ultra bag which has been specifically designed for the job. Osprey have recently released the Talon Velocity 20 which in testing has been superb. Don’t be tempted to get a bag that is too large, remember, the more space you have, the more you may take.

Bottles are the obvious way to carry water, typically 2x 750ml on the chest straps. I personally really dislike this format, I find it uncomfortable and unpleasant. So, find your own solution. Bladders have always been considered a NO for MDS but I personally find the solution ideal for my multi-day adventures. If you are a ‘racer’ this is not the best solution, but for most, it is ideal. As always, bladders can puncture, so, think about this.

Correct shoes and gaiters are essential. ©iancorless

Shoes will always be a debate and point of discussion. Shoes are personal and must be suited to you, the individual. Consider your gait (neutral, supinate or pronate), consider time on feet, consider your weight, consider how much you will walk (and then double it) also consider shoe drop and how much cushioning you need. It’s impossible to recommend any one shoe because of these variables. You will see top runners using a lighter shoe, remember, these shoes only need to last 20-30 hours. However, you may well need a shoe for 40, 50 or 60-hours. Do you need a trail shoe? No, you don’t need a trail shoe but I would say that many trail shoes are more durable as they are designed for the rough and tumble of variable terrain. Do you need an aggressive outsole? No, you don’t, but I do think some grip is better than none and therefore I would use a trail shoe over road. Protection? Toe box protection is a good idea as deserts include lots or rocks, far more than you may think. Do I need a size bigger? Shoe sizing does depend on what is ‘normal’ for you. I always recommend a thumb nail of space above the big toe, you don’t need any more than this. Recommendations of going a size is bigger is bad advice in my opinion. A shoe that is too large allows your foot to move, a moving foot causes friction, friction causes blisters and the rest is the same old story that I see at desert races all over the world. However, I would recommend a shoe with a little more width in the toe box, this will allow for some comfort as the days progress. If you are prone to feet swelling, discomfort, blisters and so on, get a strategy sorted before you head out to your chosen race. You will need a gaiter and while not always the case, sewing velcro on a shoe can change its shape, so, consider this. There are specific desert racing shoes now available by Salomon and Raidlight.

Poles are a godsend, buy some and learn how to use them. They are 4-wheel drive.

You can be creative with food prep ©iancorless

Food is essential, make sure it works. Hot or cold water is a consideration and make sure if using meals that need rehydrating that they work with water at desert temperature. Never assume that water will always be warm because you are in the desert, just as we get hot years, we also get cool years.

Salt is needed to keep you in balance. Many foods contain salt so look to supplement that with the mandatory food cubes. Be careful here, for example, OXO works considerably better than Knorr. Do you need alt tablets? Do your research,, find out what you personally need and come up with a plan. Listen to a podcast HERE.

Avoid this! ©iancorless

Feet – make sure you look after them. With the correct socks and correct shoes, there is no reason to get blisters and despite what some people say, the majority of people do not get blisters. Read Healthy for Running and Walking.

Heat is difficult and without doubt, it’s better to adapt to heat before the race. Read about Heat Acclimation by Dr Jodie Moss.

Hygiene is crucial and difficult when self-sufficient. But set up a protocol not only for your benefit but for those around you.

Luxuries keep them to a minimum.

Toilet paper is essential, make sure you have enough and compressed towels are brilliant to freshen up when you add a little water.

Take essentials on the plane and wear your run apparel and shoes. That way, should a baggage disaster happen your chances of racing improves.

Have additional items such as a base layer, sleeping bag liner and other items that may be on a ‘question’ list for the race. On night 1 and before you go to admin, you can make final decisions of what to and what not to take. Particularly important if you think you may be cold at night.

What a journey ©iancorless

FINALLY

The medal! ©iancorless

You signed up for the challenge, you wanted to be on the start line and therefore you are responsible for the outcome. Believe me, the ‘you’ that leaves the Sahara is not the same you that entered. Arguably, you change the moment you pay the deposit, the transformation process begins. Embrace the journey and apply yourself. Keep perspective, the MDS journey is an enhancement of you as a person. It’s easy to become obsessed, ultimately the majority of runners at MDS are enthusiasts, if you keep that in mind the journey will be a complete one.

Plan ahead, formulate a long term plan and don’t rush. The sooner you start this process, the greater your chance of success and the less chance of injury. Plan stepping stone races and don’t be fooled into thinking that you need to run marathons day-in and day-out. You don’t! Training is about ALL the training you do and not about anyone run.

Commitment, training and dedication. ©iancorless

If we exclude the top 50-100 runners (who will also walk sometimes) the majority of the MDS field spend a huge amount of time walking. Learn to walk! Believe me, it’s a huge tick in the MDS box and rest assured that if you are able to walk at a good consistent pace (barring injury or dehydration) you will finish MDS.

MDS is an inclusive experience ©iancorless

You are going to share bivouac with other people and you are going to have some serious highs and lows. These tent mates will pull you through and motivate you. They will become friends for life.

Legs, lungs, heart and feet will only get you so far. The mind is what will get you to the finish. Despite the hardships and pain, embrace the journey and mentally prepare for the challenge.

You. A pack. The desert. ©iancorless

MDS is a magical and life changing journey, it really is a true challenge of mind and body to race over many days, irrespective if you complete or compete. It’s a hark back to a more primitive time, a time without clutter and modern technology. Embrace this. Embrace the silence of the surroundings and the simplicity of placing one foot in front of the other, eating, resting and sleeping and then doing it all again.

MDS Morocco 2024 – Stage 1

Bivouac in the distance towered by the ominous weather

The 2024 MDS Morocco officially got underway after a day of strong winds, sandstorms and rain through the night.

With the glow of fires in bivouac, the sky was ominous and the flashes of light and sound in the distance was a warning of what was to come.

A river runs through it

Stage 1, 24.7km and 507m+ was in theory, an easier day passing through very familiar MDS territory. With 2.5km´s of easy terrain before a short sand climb and descent before a long flat section to cp1.

Climbing the early pass before the rain came

Cp1 to Cp2 contained more soft-sand and soft-sand followed as the runners climbed to the highest point via a mountain pass and then a descent all the way to bivouac.

Making a splash

The story of the day was the weather, the ominous clouds and distance sounds moved to bivouac and then reached the first mountain pass just as the last runner came through.

The fagility of nature

What followed was nothing short of a biblical downpour turning certain sections of the stage 1 route into a mud bath of flooding, rivers and streams. Cp2 was hit hard, but participants embraced the challenge. Everyone was smiles, fully understanding that they were experiencing a very unique moment in MDS history.

As quickly as the storm came, it disappeared and as the day passed, by midday, skies were blue, the sune was once again beating down and all was resumed for a typical MDS day!

Full MDS Morocco results are available to be viewed HERE

El Morabity after cp2 in the rain

Top 3 for stage 1 came as no surprise for the men with Elmouaziz and El Morabity playing a game setting up Rachid for the long stage tomorrow.

2 – Rachid EL MORABITY 2:12:20

3 – Thomas Benjamin BERTIN 2:13:25

For the women:

1 – Lucie MATT 3:02:22

2 – Emilie GARCIA 3:16:40

3 – Délia CLAVIEN 3:21:11

A unique day in the Sahara

The HANDI race started with the masses and proceed for 1km before transferring via vehicle to Cp1. They then move from Cp1 to Cp2, km8.5 to km12.2 in ´race mode.´ A tough and arduous challenge moving a special wheelchair through the soft sand of the Sahara. One pushes, the other pulls. It’s incredible to see these 10 pioneering teams pave a new way in Morocco.

Inspiration from the Handi teams

Tomorrow, stage 2, which is the theoretical long day. Athletes can choose, 20km, 40km or 60km. However, after the heavy rains of today and localised flooding, there may be a change of routes.

Rivers suddenly appeared

Half Marathon des Sables Fuerteventura – New Event

fullsizerender

Marathon des Sables, the iconic multi-stage race has finally, after 30-years expanded with a new race for 2017 – HALF MARATHON DES SABLES FUERTEVENTURA.

The event will echo the ethos of the iconic ‘MDS’ race providing a 3-day self-sufficient journey of 120km’s on the Canary island of Fuerteventura.

Pre registration is open and although the event will take place in September, specific dates have not yet been confirmed.

halfmds

The MARATHON DES SABLES organisation and Fuerteventura present a new challenge: the HALF MARATHON DES SABLES FUERTEVENTURA. This 120 km running race in three steps will be held on September 2017, in Fuerteventura, in the Canaries Islands. As the MARATHON DES SABLES, it will be a food self-sufficiency race.

Unlike the the legendary benchmark multi-stage father figure race, Marathon des Sables, the new ‘half’ edition is designed to provide an entry level race at a much more affordable price. Where families may be able to join a racing father or mother and enjoy what Fuerteventura has to offer while a parent or parents race.

Although not confirmed, it is anticipated that entry per person will be under 1000 euro and places will be limited to 500.

(I must stress, this price and entry places are not confirmed yet)

Inscriptions for the race are HERE and as stated, it is expected that they will be limited.

TNFUTMB need points?

UTMB

Today the TNFUTMB organisation is going further by testing the creation of a mark, which will allow training courses to be a source of points, according to very strict criteria. This course is organised this year in partnership with WAA.

Qualifying courses with WAA

WAA, (What An Adventure), an enterprise which focuses on two activities: training and sports merchandise.

WAA Ultra Training has, for several years been organising courses in collaboration with, amongst others, Vincent Delebarre (winner if the UTMB®) for the mountains and Laurence Klein (multiple winner of the Marathon des Sables) for the desert…WAA Ultra Equipment offers ranges of products in the colours of the partner races such as Ultra-Trail du Mont-Blanc®, the Marathon des Sables, or even the Eco-Trail de Paris.

This year the WAA, for  several years a partner with the  UTMB® are opening the way by setting up, under the aegis of the organisation, a new concept of training courses for preparation for the UTMB®, CCC®  or TDSTM valid for any long trail race which is run in the mountains.

The mountains as well as being beautiful can be hostile, difficult and changeable …The potential risks are numerous but it is possible to anticipate them when they were identified and when one is ready for them. So, the Ultra-Trail ® course will offer apart from a reconnaissance of the terrain, physical training and real ‘mountain’ environment training: “Safe” behaviour, good practise in respect for the environment, race management to optimise performance allowing the runner to be the key to his own safety.

Vincent Delebarre‘s testimony: “For 8 years I have organised around fifteen courses each summer which allow me to judge the physical condition and above all the knowledge of the activity and the participants’ environment. And there is still a lot to be done. The qualifying races show the level of experience relating to trail -running but for all that do not confer, the minimum  knowledge of good management and comportment in the mountains : knowing what to do, how to react in case of injury, or storms, how to help a wounded person in the cold or under the sun… These courses offer the training necessary for a trail runner to become autonomous because trail-running is not just simply running but also integrating into the surrounding environment.”

The courses earn up to 3 qualification points

The Ultra-Trail® courses allow for the possible acquisition of 3 qualifying points, validation average from both the leader and an external jury. But following the example of « Mont-Blanc courses » in the mountains (courses of 5 days preparation and acclimatisation aiming at the ascension of Mont-Blanc), the awarding of points, same as the arrival at the summit of Europe, is not guaranteed. Bad weather conditions, limited physical condition or insufficient technique can lead to an absence of points. Participation in the courses does not mean automatic acquisition of points.

For these courses in the absence of the idea of the competition, the physical and mental load imposed is equivalent to a trail-running event worth 3 points. To obtain this qualifying recognition, the level of these training courses is very high and the qualities required to participate in it are important: being capable of doing the UTMB ® route at the speed of the official time barriers, having the endurance required for each of 4 stages, of having a minimal experience of the Mountain environment…

As for their progress in stages, the notion is already known and used, since today certain big races with stages like the Marathon des Sables, the Défi de l’Oisans, the Annapurna Mandala Trail, the Desert Oman Raid, the Transrockies run or even the Grand to Grand Ultra… are qualifying and already carry points. Also the number of points from the Ultra-Trail®training courses is determined on the basis of the calculation which is currently used for these races and takes into account the kilometres, positive height gain, number of stages and their difficulty, the time barriers, etc.

Michel Poletti confirms that: « Having tested the courses lead by Vincent Delebarre has run for several years, they demand the physical and mental engagement which is as important as that of a race in stages. They carry a qualitative education on the practice of the trail-running in the mountains (effort management, learning to be autonomous, safety, and respect for the environment…). Beyond just training they can allow the acquisition of the necessary Mountain experience, just as much as by their participation in a race. ».

A professional and economic dynamic

An information day « trail-running in the mountains » is being organised by the WAA, Vincent Delebarre and Jean-Claude Marmier with the aim of explaining the context of these courses, the stakes and the tolerated levels required by the leaders. It is aimed at, firstly, around ten mountain professionals who because they have the specific information, can supervise the Ultra-Trail® training courses.

The organisers are going even further, by imagining eventually a training which could deliver an additional and specific mention “mountain trail-running” for professional guides or leaders…who would like to organise courses themselves. A discussion is planned with the National School of Ski and Mountaineering to see if it is possible to envisage a collaboration for this training to become recognized speciality, and offered by the mountain careers sector.

Trail-running is today a rapidly expanding phenomenon which is generating an innovative energy urging the development of the discipline and all its players. It is the vector of an economy at every level offering mountain huts, municipalities, guides and race organisers very positive perspectives.

I would be really interested to hear your thoughts and comments on this?
