Countdown to MDS The Legendary 2025 – Issue One

Posted on March 1, 2025 by talkultra

The 2025 edition of the Marathon des Sables – The Legendary is getting close, as we journey through March, we will post weekly articles to help you fine tune your preparation.

Following on from the 2024 edition, the longest in MDS history, the 39th 2025 edition will follow a similar format and distance. The event will take place over 6-stages/ 7-days and notably, the ‘long day’ was stage 3 in 2024, for 2025 it will return to stage 4.

All 6-stages will be timed as in 2024, previously, the charity stage was not timed.

Although the race has fluctuated in distance over the years, a distance of +/- 250km’s should not come as any great surprise and training in the build up to the event should have been planned with this in mind.

6 timed stages does make a considerable difference and that should be considered. In 2024, the long day coming on stage 3 was an extra challenge, for 2025, it returns to stage 4! Depending on how fast you complete the long day, you can have a full day and night as recovery before stages 5 and 6.

Daily distances are typically never disclosed before the race and the jury is out if the distances will be announced pre arrival in Morocco, watch this space! However, it is pretty easy to guess on approximate distances.

The 2025 MDS Legendary will look (potentially) like this:

Stage 1: 32km (day 1) running total: 32km
Stage 2: 38km (day 2) running total: 70km
Stage 3: 36km (day 3 running total: 106km
Stage 4: 80km (day 4 and 5) running total: 186km
Stage 5: 42km (day 6) running total: 228km
Stage 6: 21km (day 7) running total: 249km

Total: 249km

Three key considerations:

Expect more sand, anticipate no Djebel El Otfal and expect Merzouga Dunes. With the above information, you now have at least a template and guide for which to plan around.

“…and for sure it will be tough, I am not going to tell you that it will be easy! The distance will be 250km’s, I am little unhappy because I cannot put the long stage in the third position, I loved this last year, but according to our plan, we need to move it to the fourth stage. It will be tough, very tough and really beautiful. We have some amazing places planned, 80% is new tracks. You will see places never seen before in any MDS. There will be no El Otfal, there will be lots of sand and yes, Merzouga will return.” – Cyril Gauthier

BIVOUAC

Remember, from the moment you arrive in bivouac you are self-sufficient. So make sure you bring food/drink (water is provided) to cover the days before the race starts. This food can be in any form and weight as you do not need to carry it, so, be creative. Rachid for example makes a Tagine in camp…!

Also remember, you have your luggage with you before the admin protocols. So, bring extra items, warm layers, spare kit etc. That way you can fine tune equipment in a real situation. Particularly helpful when judging climate conditions. DO NOT assume that it will be hot, recent history has shown that temperatures and conditions in the desert are changing – MDS Morocco in October had rain and flooding. The recent MDS Morocco Atlantic Coast had extreme wind, cold temperatures and rain. Be prepared!

ADMIN DAY

You will have your luggage with you in bivouac before admin day. You can make last minute adjustments if required. Be prepared and make sure you comply with all rules and regulations. A pack must have a minimum weight of 6.5kg PLUS water (1.5L). You must have a minimum of 2000 cals per day. You must have ALL the mandatory kit.

SALT

The new revised mandatory requirement for the race requires 14 broth cubes – these cubes are known to be salty. You have no choice here, you must have them. In 2024 many questioned the validity, however, during and post the event the general consensus was very positive. Take note here, not all cubes dissolve the same in water, so, make sure you find a cube that works such as Knorr. My advice is to plan a strategy that works for you. Listen to my podcast with Andy Blow from Precision Hydration HERE. Remember, this is a self-sufficient race, so, be prepared to be self-sufficient and have a plan/ strategy that works for you.

WATER

Another key change from 2024 is water and how it is provided. In principal, once you start on stage 1, water is unlimited. No longer are you provided 1 or 2 1.5ltr bottles at checkpoints. Now, the blue coats will pour water from jugs in to your bottles. If you stand at a CP and then drink a full bottle, it will be refilled.

Another key note to consider is that should conditions dictate or should the organisation think that additional water will be helpful, water stations may be added between CP’s. This is very important. Typically (conditions and terrain allowing) CP’s are 10km’s apart, therefore, you may heave an additional water station at say 5km’s.

The long day may (tbc) have a requirement that you can carry extra water capacity? This extra water would potentially be provided in a 1.5ltr bottle, so, either have an extra bottle to decant this to, or, have a system to carry a 1.5ltr bottle.

After the stage finishes, water is then rationed and you are provided with 1 large 5ltr bottle. This water will be needed for your hydration post stage, cooking dinner, cooking breakfast and your water allowance to CP1 the following day. If you want to wash, that also comes from the 5ltr allowance, so, make sure you drink and eat and understand what water capacity you need before taking a wash.

FEET

Along with dehydration, damaged feet are a key reason NOT to finish MDS. Make sure you have correct fitting shoes, the right socks for you and you know how to look after your feet. Read HERE and HERE.

SAFETY

MDS has strict protocols for your safety. You will see fast response vehicles (buggies) designed to gain fast access to the most difficult and challenging parts of the desert. In addition, there are 4×4 vehicles situated throughout the course.

Each runner is using a tracker attached to their pack. This allows MDS to follow you and keep an eye on your position, it also has an emergency button which notifies the MDS team of your need for immediate response and attention.

There are also medical runner’s. These are trained medical staff who will participate during the race. They will be on the course with you and in certain scenarios, they are able to provide immediate care or attention to those who need it. They have a different coloured number so you can identify them.

Medical team personnel are trained and equipped to provide immediate attention at any location within the desert.

Finally, water is not rationed during the race, so, if you need more liquid, you can have it! Also, at key CP’s, iced water is available to enable cooling. This will be poured on your head via a blue coat volunteer. Orange jackets handle medical emergencies.

MANDATORY EQUIPMENT

Needless to say, despite what some believe, but mandatory equipment is mandatory!

Pack such as WAA Ultra Bag 20L
Minimum capacity of 1.5 litres of water
Sleeping bag
Head torch and spare batteries (you can have a charger/ solar charger)
10 safety pins
Compass with 1 or 2 deg precision
Lighter
Whistle
Knife
Topical disinfectant
Signal mirror
Survival blanket
14 cubes of broth
Sun cream
200 euro or 2000 dirhams
Passport or ID card
ECG (original doc) and medical
Roadbook (supplied on arrival)

Make sure you comply with the very strict regulations and timeline in regard to ECG and medical form.

FOOD

You need ** 14,000 calories of food, 2000 calories per day. However, 12,000 is mandatory. You can of course carry more than this, but I consider 14,000 is the minimum with the rest day. You must be able to prove the calories, so, if you decant food into lighter or different packaging, make sure you keep the nutritional information.

** Adding as clarification:
2000 calories per day, it’s a 6 stage race
BUT remember the rest day.
I see the calories as below BUT YES 12,000 cals to comply with rules.
Stage 1 : 14,000 cals – Day 1
Stage 2 : 12,000 cals – Day 2
Stage 3 : 10,000 pls – Day 3
Stage 4 : 8,000 cals (the long day) – day 4
Day 5* : 6,000 cals (rest day)
Stage 5 : 4000 cals – Day 6
Stage 6** : 2000 cals – Day 7
*Day 5 you may still be running/ walking and/ or in camp for the rest day and will need 2000 cals.
**Stage 6/ day 7 you technically only need breakfast and snacks for the stage.

WHAT YOU NEED

In addition to mandatory equipment and food requirements, you need essential items to complete the race. Use the list below as a guide:

Run top (maybe with long sleeves)
Neck roll/ Buff
Run shorts/ skirt or similar
Socks (plus maybe spare socks)
Shoes with gaiters (make sure you have the gaiter velcro sewn on well in advance)
Hat (consider cover for the neck too)
Sunglasses (make sure they have good protection and if they fit well for protection in sand storms)
Watch
Warm layer (windproof and maybe lightweight down jacket)
Foot care
Hygiene products
Toilet roll/ wipes
Lip balm
Blind fold
Ear plugs
Spoon
Pot/ bowl*
Stove**
Fuel cubes**
Sleeping mat
Pillow
Flip flops or similar

**Stove and fuel only required if you plan to heat water

*Pot/ bowl or similar will be required as now it is no longer possible to cut down a 1.5ltr bottle

Recommended

Many things can happen in a self-sufficient race and yes, equipment can fail. So, think about on-the-go repairs and what you may need.

Zip ties
Gorilla tape
Super glue
Sewing kit
Cord/ thin rope

Top Tips

Keep the pack weight as close to the minimum 6.5kg as possible, additional weight is additional stress that you do not need.

Keep luxuries to a minimum, they only add weight. A super light Mp3 player (with good battery) and earphones is the only luxury I would consider.

Accept that this is a tough challenge, you will be stripped back to a survival mode. You may not wash, you will get dirty, you will get smelly. Accept it.

Start slow and ease into the race.

Poles can be a lifesaver and I recommend them but you must learn to use them. Those at the front do not need poles, they can run.

Learn to walk, walk and walk. Many go to the desert with the expectation of running 80% and walking 20%. The reality is it will be the other way around.

Look after your feet and start with the correct shoes for you.

Take a sleeping mat or pad. You only need to do three things: run, eat and sleep. Sleep and comfort is important for recovery.

Make sure you check the full rules and regulations HERE

Marathon des Sables – The Legendary : NEWS THREE – Feb 2024

Posted on February 19, 2024 by talkultra

Marathon des Sables is a simple race that often becomes over complicated by too much information. Take advice, look at websites, process the information but importantly find out what works for you. We are all individual, what works for one may well not work for another.

When you break the race down, here are my TOP 20 TIPS of what to focus on for Marathon des Sable – The Legendary.

Pack – Ideally needs to be as small as possible and as close to the minimum 6.5kg weight when packed. There are many packs out there and just like clothing, packs fit in different ways, so, it is important to try many to find the best for you. I size between 20-25 Ltr is ideal. Key things to look out for: easy access to water, easy access pockets for snacks etc, adjustable to get perfect fit, minimal bounce when loaded, flexibility to compress the pack and make smaller as you reduce the contents (food you eat) as the race progresses.

Sleeping bag – Needs to be lightweight, small when compressed and warm enough for you based on your warmth requirements – are you a cold or warm sleeper? Popular sleeping bags are PHD, Nordisk Y, OMM, Sea to Summit, Western Mountaineering, Rab etc. Take care on the ‘comfort’ rating and I have an in-depth article on choosing a sleeping bag HERE.

Jacket – I always recommend a sleeping bag and jacket as opposed to just taking a sleeping bag. MDS can have cooler editions, particularly early morning or evening and having the option of a jacket is great. It also means that you can potentially take a lighter and less warm sleeping bag as the jacket can add as an additional warm layer. As an example, a Sea to Summit SP1 bag and a Haglofs L.I.M Essens jacket weighs 510g! Many brands do sub 200g jackets, look at Haglofs, Mont Bell and Y by Nordisk.

Clothes – You just need what you will run in. However, a spare pair of socks is commonplace. No need to get new clothes and don’t worry about colours. The most important is that they are comfortable and they do not rub or chafe.

Sleeping Matt – Optional but a good nights sleep is important for recovery. There are only three things to do at MDS, run, eat and sleep. Make the sleep as comfortable as possible. Two options exist – inflatable and solid foam. The choice is yours. The inflatable ones offer more comfort, more flexibility in packing but with poor admin, you do run the risk of a puncture. Recommended Sea to Summit HERE

Shoes and Gaiters – Shoes are personal and if you already have shoes that are comfortable and cause no blisters, then you have the perfect MDS shoe. Things to consider, a wider toe box is good to allow toe splay, a thumb nail of space above your longest toe is adequate, no need for more, and make sure they have enough durability for you! I say ‘you’ because Rachid El Morabity will complete the whole race in 21-hours whereas most people won’t even do just the long day in that time – his shoe shoe choice will and can be very different to what most of us need! Get your Velcro sewn on your shoes and make sure that when you get the shoes back the fit has not been altered.

Food – You need a minimum amount of calories per day specified in the race rules (2000 per day) and how those calories are made up are up to you. This for many is a difficult one. It raises many questions and yes, it’s good to find out what other people do and use but ultimately, YOU have to eat it. Food is the heaviest item you will carry, but remember, your packs gets lighter each day as you eat the contents. Re-packing food can save weight and space. Think about the the balance between carb, protein and fat and importantly, what tastes good at home, may not taste good in the Sahara.

Stove – The decision to use a stove is another question mark but it would appear that most runners like that hot water option. Remember though, you can make a fire from twigs, shrub and branches that surround bivouac.

Pot – Many use a 1.5 ltr water bottle cut down as a food bowl. For the 2024 MDS, 1.5 ltr bottles will not be supplied, so, you will need a suitable pot. Esbit for example do a small titanium pot with lid.

Water – You must have the capacity to carry 1.5 ltr of water and for the long day, 3 ltrs. Water is provided by the race. For 2024, water will not be provided in 1.5 ltr bottles but will be distributed by staff at the cp’s using jugs to decant water from larger 5 ltr bottles. On the long day, an additional 1.5 ltr bottle will be provided either at the start or cp1.

Salt Tablets – Salt tablets will no longer be provided at the race and you now must have a mandatory 14 stock cubes. Of course, you are recommended to work out your electrolyte needs and plan accordingly. You are welcome to take your own salt tablets or similar product such as those provided by Precision Hydration.

Feet – Look after them, along with dehydration, blistered and damaged feet are a key reason for failure in any multi-day race. Prepare them before the race especially trimming nails back and knowing what socks work for you. After each day in the race, clean feet, allow them to breathe and look after them. Get any sore or hot points addressed immediately.

Mandatory kit – You are supplied with a mandatory kit list and you MUST have everything on that list. Please note, for 2024 the venom pump has been removed and you must have 14 cubes of broth.

You – 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. 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. The legs, lungs, heart and feet will only get you so far, then the mind will take over. Mentally prepare for the challenge ahead and make mental plans for how to survive and motivate yourself when the going gets tough. Laugh when you hit rock bottom. Laugh when you are going the toilet in a brown plastic bag. Laugh with and at your tent mates and fellow runners. The comradeship of MDS is quite unique, embrace it.

Training – Plan ahead, formulate a long term plan and aim for consistency.

Walking – Learn to walk. Many think they will run 80% and walk 20%, if you are lucky, it’s the other way around. Make walking a positive, make walking fast, make walking productive.

Poles – For many, poles are a huge advantage. They are like 4-wheel drive and without doubt, they make you walk faster. But you must train with them and learn how to use them.

Shoes – NEVER take advice from anyone online that tells you that ‘X’ is the shoe to wear for MDS unless they know you and your run style. Forget the advice about going up a size or two sizes. It’s a recipe for disaster unless you know that your feet swell? A shoe that is too big will allow your foot to move, a moving foot causes friction, friction causes blisters and the rest of the story speaks for itself. General advice is that if you have a ‘thumb nail’ of room at the front of the shoe above the longest toe, this generally works. Notice I say ‘generally’ – there are exceptions. One thing that may happen, is your foot may get wider (rarely or never longer) with the heat and additional time on feet, therefore a shoe with a wider toe box often works well for many runners.

Equipment – Minimum pack weight is 6.5kg plus water, get as close to this as you can. Additional weight is additional stress and just makes the journey harder. Luxuries are ok if they improve the journey and make it easier, music is a good example of an additional extra. I can’t really think of anything else…

Friends – Tent mates will pull you through and motivate you. They will become friends for life. Ideally find tent mates before you head out to the Sahara and plan your tent group.

Admin and preparation that you may not think of:

Take essentials on the plane and wear your run apparel and shoes. That way, should a baggage disaster happen your chances of racing improve.
Take food with you for the travel and on the plane.
The journey from the airport to bivouac 1 can be lengthy be prepared with your own snacks and drinks. MDS do provide a packed lunch.
Night 1 and night 2 in bivouac are NOT self-sufficient so take extras such as an inflatable bed, food and luxuries that you are happy to give away to the berbers. May as well have 2 comfortable nights and a comfortable day before the racing starts.
Food before the race starts is now down to you. Be prepared to have plenty of variety and remeber, within reason, this can be anything!
Admin day can be lengthy multi-hour experience. Take water and snacks for when standing in line and maybe take an umbrella so you have shade.
Keep sun screen on and keep hydrated. No need to drink vast volumes – drink to thirst before the racing starts.
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.
Remember that after bag drop and check-in you have no access to any additional items, however, you only become completely self-sufficient when you start the race. With that in mind, you can have additional food and luxuries with you until day 1 kick-off, it’s a useful tip and does mean that you can have additional comfort for a good 12-hours.

Conclusions:

Marathon des Sables is a magical and life changing journey as are most if not all multi-day races. It really is a true challenge of mind and body to race over many days, irrespective if you complete the race in just over 20-hours or 60+ hours. 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.
