COUTDOWN TO MDS LEGENDARY 2026 – ISSUE TWO

Marathon des Sables: What Actually Matters

The Marathon des Sables has a way of becoming far more complicated than it needs to be. Spend five minutes online and you’ll find spreadsheets, gear breakdowns to the gram, and endless debates about socks.

Here’s the truth. It’s a multi-day race in the desert where you carry your own kit, manage your energy, and keep moving forward. That’s it.

Yes, details matter. But simplicity wins.

The 2026 Marathon des SablesThe Legendary is not just another year in the desert. It marks 40 years of the race. That alone tells you something about what’s coming. This edition matters. It will be longer, tougher, and built to celebrate the history of the event properly.

As we move through March, I will release weekly articles to help you sharpen your preparation. This is the second of four. The aim here is simple: give you clarity. No surprises. No guesswork.

Below is a broader, more grounded take on what to focus on, including some of the small, often overlooked realities that make a big difference once you’re out there.

Start With This Mindset

You are not preparing for comfort. You are preparing for control.

Control of your energy.

Control of your hydration.

Control of your thoughts when things get hard.

The desert strips away noise. What’s left is you, your pack, and the next checkpoint.

1. Your Pack: Fit Over Fashion

You’ll see a lot of the same packs on the start line. The WAA 20L Ultra Bag is extremely common because it was built specifically for races like this.

But popular doesn’t mean perfect.

A pack should sit close to your body without bouncing. It shouldn’t pull on your shoulders or rub your lower back raw by day three. Try it loaded. Walk in it. Run dunes in it if you can.

Smaller is usually better. If you give yourself space, you’ll fill it. And once your food weight drops midweek, too much space means constant shifting and irritation.

Getting close to the 6.5 kg minimum isn’t about ego. It’s about reducing cumulative fatigue. Every unnecessary gram is lifted thousands of times over the week.

2. Sleep Is Recovery, Not Luxury

You don’t need a five-star sleep system. But you do need rest.

A sleeping bag choice should reflect how you actually sleep at home. If you’re always cold, don’t suddenly become brave in the Sahara. Cold nights drain energy quickly.

A lightweight down jacket is incredibly useful. Brands like Mont Bell, Haglöfs, Yeti, and Nordisk all make reliable options. It doubles as camp insulation and extra warmth inside your bag.

Random but important: cover your head at night. Even a simple buff makes a difference.

And yes, take a sleeping mat. After several hours in the heat, lying on hard ground feels far less heroic than it sounds.

3. Clothing: Function Only

Nobody cares what you look like by stage four.

Choose clothing you’ve already trained in. Check underarms, inner thighs, lower back, and anywhere straps sit. If something rubs slightly at home, it will tear skin in the desert.

Photo by Ian Corless

A spare pair of socks is wise. Changing into dry socks after a long stage feels surprisingly restorative.

Some runners like having a lightweight long sleeve or leggings just for evenings. It’s less about warmth and more about feeling human again after a tough day.

4. Shoes and Gaiters: Non-Negotiable

Shoes must be tested, broken in, and reliable.

Slightly wider can help accommodate swelling. But oversized shoes create movement. Movement creates friction. Friction creates blisters.

Aim for a thumbnail’s space beyond your longest toe.

Gaiters are essential. Sand will find its way in otherwise, and constant grit inside your shoe is demoralising.

Small thought: practise emptying sand quickly and calmly. You’ll do it often.

5. Food: Think Beyond Calories

Yes, you must carry at least 2,000 calories per day.

But calories alone aren’t the whole story. Appetite changes. Sweet fatigue is real. By midweek, many runners crave savoury food.

Bring variety. Something crunchy. Something salty. Something soft. Texture matters when you’re exhausted.

Recovery nutrition right after each stage can speed up how you feel the next morning. Even a small protein-based drink helps.

Also consider practicality. If you skip a stove, make sure your meals work with cold water. And if you’re someone who needs coffee to function, plan for it. Tiny comforts can have a big psychological impact.

6. Water Strategy: Be Flexible

You must be able to carry at least 1.5 litres, usually via two 750 ml front bottles.

Soft flasks and bladders are lighter, but they can puncture. Rigid bottles are heavier but durable.

Have the capacity to carry an additional 1.5 litres if required. In extreme heat or on longer stages, the race has sometimes increased water allowances.

Practice drinking steadily rather than chugging. Drink to thirst before the race starts. Overhydrating early doesn’t help.

7. Salt and Electrolytes: Plan It Yourself

Salt tablets are no longer handed out.

You must start with 14 stock cubes as part of the requirements, but that’s just one element. Test your electrolyte strategy in training. Don’t experiment for the first time in Morocco.

Cramps in the middle of a long stage are not where you want surprises.

8. Your Feet: Your Entire World

If your feet fail, your race fails.

Trim nails carefully before the event. Know which socks work for you. Consider taping strategies only if you’ve tested them.

After each stage:

  • Remove shoes immediately.
  • Clean sand off.
  • Let skin dry.
  • Deal with hot spots early.

Blister management is part of the race. The medical team is experienced, but prevention is always easier than repair.

9. Heat Preparation

The final two weeks are ideal for heat acclimation.

Sauna sessions. Hot baths. Controlled heat chamber work. Even Bikram yoga.

The goal isn’t to exhaust yourself. It’s to teach your body to manage elevated core temperature more efficiently.

Arriving heat-adapted reduces stress from day one.

10. Taper Properly

In the final weeks, you don’t gain fitness. You protect it.

Reduce volume gradually. Stay mobile. Stay healthy. Combine tapering with heat work.

You want to feel slightly restless at the start line, not tired.

11. Learn to Walk Well

This surprises many first-timers.

You may not run as much as you think. Dunes, heat, pack weight, and long stages change expectations quickly.

Photo by Ian Corless

Practice strong, efficient walking. Especially uphill. Keep posture tall. Use arms deliberately.

Fast walking wins time and saves energy.

12. Poles: Train With Them or Leave Them

Poles can feel like four-wheel drive in soft sand and on climbs.

Lightweight folding carbon poles from brands like Black Diamond and Leki are common.

But poles only help if you’ve trained with them. Poor technique wastes energy. Good technique saves it.

13. Keep Equipment Minimal

Every “just in case” item adds up.

Ask: will this meaningfully improve my race?

Your pack should sit close to 6.5 kg. The only luxury many runners truly appreciate is a lightweight way to listen to music.

Interestingly, many also discover they don’t miss their phone at all.

14. Tent Life

You’ll share a tent with seven others.

These people become your support system. You’ll hear their breathing at night. You’ll see their low moments and your own reflected back.

Choose tent mates wisely if you can. The camaraderie becomes one of the most powerful parts of the week.

15. Travel and Admin Realities

Wear your running shoes and kit on the plane. Carry your pack as ‘carry-on’ with as much of your race kit as possibe. Lost luggage does happen.

Bring your own snacks for travel days. The transfer from Marrakech is quite long, so is the transfer to bivouac one. MDS do provide lunch packs as and when applicable, always good to be self sufficient.

The first two nights in bivouac are self-sufficient, plan accordingly for food. Take comfort items you’re happy to give away before racing begins, for example, you may take a larger/ heavier inflatable bed.

Admin day can take 1-2 hours. Bring water, snacks, sun protection, even an umbrella for shade. Stay patient.

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.

After bag check-in, you drop your luggage and no longer have access to extra gear. Make sure you have everything you need for the race! But full self-sufficiency only begins when the race starts, so you can enjoy small comforts until then.

Bring a simple repair kit. Zips break. Gaiters tear. The desert is unforgiving.

16. The Mental Game

At some point, you will question why you signed up.

That moment passes.

The Marathon des Sables isn’t just about endurance. It’s about staying calm when you’re tired. Staying steady when others surge. Accepting discomfort without drama.

Highs and lows are part of the rhythm. If it were easy, it wouldn’t matter.

Final Thought

The desert simplifies everything.

There’s no clutter. No constant notifications. No daily noise. Just sun, sand, wind, and the quiet focus of moving forward.

Whether you finish near the front or close to the cutoff, the experience is transformative.

It reminds you how little you actually need, and how much you’re capable of carrying.

MDS is 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.

COUTDOWN TO MDS LEGENDARY 2026 – ISSUE ONE

Photo by Ian Corless

The 2026 Marathon des SablesThe Legendary is not just another year in the desert. It marks 40 years of the race. That alone tells you something about what’s coming. This edition matters. It will be longer, tougher, and built to celebrate the history of the event properly.

The Shape of the 2026 Race

If you raced in 2025, you already experienced the longest edition in MDS history. In 2026, the format stays similar but the distance increases again.

Six stages. Seven days. All timed.

Photo by Ian Corless

In previous years, the charity stage was not timed. That changed in 2025 and continues in 2026. Every stage now counts.

The long stage returns to Stage 4, just as it did in 2025. This time it will be 100km. Read that again. One hundred kilometres across two days in the desert.

Photo by Ian Corless

While total distance has fluctuated over the years, 250km has often been the benchmark. For 2026, you should plan for approximately 270km plus or minus. It should not shock you. But it will test you.

One positive? Depending on how quickly you complete the long stage, you may have almost a full day and night to recover before Stages 5 and 6. That recovery window could be valuable.

Daily stage distances are rarely confirmed in advance. It remains unclear whether exact distances will be released before arrival in Morocco. Historically, that information is kept quiet. Still, it’s not hard to estimate how the race could look.

Photo by Ian Corless

A likely outline might be:

Stage 1: 32km (Day 1) – total 32km

Stage 2: 38km (Day 2) – total 70km

Stage 3: 36km (Day 3) – total 106km

Stage 4: 100km (Days 4 and 5) – total 206km

Stage 5: 42km (Day 6) – total 248km

Stage 6: 21km (Day 7) – total 269km

Total: approximately 269km +/-

As in 2025, expect sand. A lot of it. Expect the Merzouga Dunes. Do not expect Djebel El Otfal.

You now have a working template to mentally prepare for the challenge ahead.

Before the Race Even Starts

Your race does not begin at the start line. It begins with logistics.

Photo by Ian Corless

In the final 2 to 3 weeks before the race, taper training back so that you are fresh and strong. Also plan for heat adaptation, this could be specific heat chamber sessions or a series of sauna sessions or similar.

Photo by Ian Corless

You are responsible for arranging your own accommodation before the official transfer from Ouarzazate to bivouac one. If you fly into Marrakech, you may need a hotel there as well. There are free transfer buses from Marrakech to Ouarzazate. Arrive in Ouarzazate at least one day before required, have a good hotel night and time to relax and prepare before the transfer to the desert. MDS will confirm the dates and times for transfers etc.

From there, the structure usually follows this pattern:

Day 1 – Bus transfer from Ouarzazate to the desert bivouac. You settle in and stay overnight. This is self-sufficient. No meals are provided. Bring enough food for arrival day and admin day. There is no weight restriction at this point, so bring what you want.

Day 2 – Technical, administrative, and medical checks. Overnight in bivouac, still self-sufficient.

Day 3 – Stage 1

Day 4 – Stage 2

Day 5 – Stage 3

Days 6 and 7 – Stage 4, the 100km long stage

Day 8 – Stage 5

Day 9 – Stage 6, medal at the finish, bus transfer back to Ouarzazate. Overnight hotel with half-board.

Day 10 – Free day in Ouarzazate, awards ceremony and gala evening. Hotel half-board.

Day 11 – Airport transfers. End of the adventure.

Bivouac Reality

From the moment you step into the bivouac, you are self-sufficient. Water is provided. Everything else is your responsibility.

You must bring food and drink to cover arrival day and admin day before racing begins. You do not carry this food during the race, so be smart. Bring proper meals. Rachid, for example, makes a Tagine in camp.

You also have access to your luggage before admin checks. This is valuable. Bring spare kit, extra layers, backup options. You can fine tune your equipment in real desert conditions.

And do not assume MDS = heat. In 2025, we had rain, strong winds and sand storms.

Recent editions have shown how unpredictable conditions can be. The October MDS 120 Morocco race in 2024 saw rain and flooding. The Atlantic Coast edition had extreme wind, cold temperatures and rain. The desert is not always hot and dry. Prepare for variation.

Before admin, you can adjust your race pack. After that, your pack must meet regulations:

Minimum weight: 6.5kg excluding 1.5 lts of water.

Minimum food: 2000 calories per day.

All mandatory kit must be present.

No exceptions.

Water Strategy Has Changed

Since 2024, water provision has evolved.

Photo by Ian Corless

Once Stage 1 begins, water during stages is effectively unlimited. You are no longer handed sealed 1.5L bottles at checkpoints. Instead, volunteers in blue coats pour water from large containers into your bottles.

If you stand at a checkpoint and drink a full bottle, they refill it.

Typically, checkpoints are spaced around 10km apart, terrain permitting. However, if conditions demand it, additional water stations may be placed between checkpoints, for example at 5km. This flexibility is important to combat excessive heat.

Photo by Ian Corless

For the long stage, there may be a requirement to carry additional water capacity. This could be supplied in a 1.5L bottle. Plan ahead. Either have spare capacity to decant, or a system to carry a full bottle.

After each stage, water is rationed. You receive one 5L bottle. That 5L must cover:

  • Post-stage hydration
  • Dinner preparation
  • Breakfast preparation
  • Water allocation to CP1 the next day

If you want to wash, that also comes from the same 5L. Prioritize drinking and eating. Washing is optional. Hydration is not.

Salt Is Now Non-Negotiable

The race rules require 14 broth cubes. They are salty and mandatory.

In 2024, this change was questioned. By the end of the race, feedback was largely positive.

Not all cubes dissolve well. Test them. Many athletes use ‘Knorr’ because it dissolves reliably. Build a salt replacement strategy that works for you. This is a self-sufficient race. You must manage your own electrolyte plan.

Feet: The Deciding Factor

Along with dehydration, damaged feet are one of the main reasons people do not finish.

Your shoes must fit correctly. Your socks must suit you. You must know how to treat hot spots and blisters. Desert sand magnifies small problems quickly.

Ignore your feet at your peril.

Advice – A thumb nail of space above your longest toe is ideal. Note, I say longest toe – this may not be your big toe! A wider shoe is a good idea to allow for toe splay. If a shoe is too big, your foot will move when walking or running. A moving foot causes friction, friction means blisters. 

Photo by Ian Corless

Make sure your shoes have gaiters so no sand can get in the shoe.

Safety on Course

The race operates under strict safety protocols.

Photo by Ian Corless

Fast response buggies are positioned to access difficult terrain quickly. 4×4 vehicles are spread across the course.

Every runner carries a tracker attached to their pack. This allows the organization to monitor your position in real time. It includes an emergency button for immediate assistance.

There are also medical runners on course. These are trained medical professionals competing in the race. They wear a different colour race number so you can identify them. They can provide immediate care if necessary. In addition, the full medical team is equipped to respond anywhere in the desert.

Photo by Ian Corless

During stages, water is not rationed. If you need more, you can have it. At key checkpoints, iced water is available for cooling and is poured over your head by blue coat volunteers. Orange jackets manage medical incidents.

Mandatory Equipment Means Mandatory

You must carry:

  • Pack such as WAA Ultra Bag 20L
  • Minimum 1.5L water capacity
  • Sleeping bag
  • Head torch plus spare batteries (charger or solar charger allowed)
  • 10 safety pins
  • Compass with 1–2 degree precision
  • Lighter
  • Whistle
  • Knife
  • Topical disinfectant
  • Signal mirror
  • Survival blanket
  • 14 broth cubes
  • Sun cream
  • 200 euros or 2000 dirhams
  • Passport or ID card
  • Original ECG document and medical certificate
  • Roadbook (provided on arrival)
  • GPS tracker

Pay close attention to deadlines and rules for ECG and medical forms. The regulations are strict.

Calories: The Real Numbers

The rules require 2000 calories per day across six stages. That equals 12,000 calories minimum to comply.

However, with the rest period during the long stage, 14,000 calories is a more realistic minimum. You may carry more. For example, a small and slight women weighing 50kg has very different calorie needs to a tall, muscular 90kg male. Understand your calorie needs.

You must be able to prove calorie totals. If you repackage food into lighter containers, keep the nutritional labels.

To break it down clearly:

Stage 1 – 14,000 calories remaining

Stage 2 – 12,000 calories remaining

Stage 3 – 10,000 calories remaining

Stage 4 – 8,000 calories remaining (long stage)

Day 5 – 6,000 calories remaining (rest day, still requires 2000 calories)

Stage 5 – 4,000 calories remaining

Stage 6 – 2,000 calories remaining

On Day 5, you may still be moving during the long stage or recovering in camp, but you still require 2000 calories. On Stage 6, you technically only need breakfast and race snacks.

Essential Personal Kit

Beyond mandatory equipment and food, you will need:

©iancorless
  • Running top, possibly long sleeve
  • Neck roll or Buff
  • Running shorts or skirt
  • Socks, and spare pair
  • Shoes with gaiters, Velcro sewn securely in advance
  • Hat with potential neck cover
  • Sunglasses with strong protection and good fit for sandstorms or take extra goggles
  • Watch
  • Warm layer – windproof and possibly lightweight down jacket
  • Foot care supplies
  • Hygiene products
  • Toilet roll or wipes
  • Lip balm
  • Blindfold
  • Ear plugs
  • Spoon
  • Pot or bowl
  • Stove
  • Fuel cubes
  • Sleeping mat
  • Pillow
  • Flip flops or similar

Note – If you plan to NOT heat water, you will not need a stove of fuel cubes. However, you will still need a bowl or something similar to eat food from.

Photo by Ian Corless

For repairs, consider:

  • Zip ties
  • Gorilla tape
  • Super glue
  • Sewing kit
  • Cord or thin rope

Equipment can fail. Plan for that.

Final Practical Advice

Keep your pack as close to 6.5kg as possible. Extra weight adds unnecessary stress, especially in the longest edition to date with a 100km long stage.

Limit luxuries. If you take one, make it a lightweight MP3 player with reliable battery and earphones.

Accept the conditions. You may not wash. You will get dirty. You will smell. That is normal

Start conservatively. Ease into the race.

Photo by Ian Corless

Poles can make a huge difference, but only if you know how to use them properly. Front runners may not need them. Most people benefit from them.

Learn to walk efficiently. Many arrive expecting to run 80 percent and walk 20 percent. In reality, it is often reversed.

Protect your feet from day one.

Take a sleeping mat. In the desert, your job is simple: run, eat, sleep. Good sleep improves recovery. Recovery keeps you in the race.

A New Year, a Milestone Season: Marathon des Sables in 2026

Photo by Ian Corless

A milestone anniversary, new formats, familiar classics, and a season that stretches from the Sahara to the Alps. Some years feel bigger than others. In 2026, the calendar alone tells you this will be one of those years for Marathon des Sables

Forty editions after its beginnings in the Moroccan desert, Marathon des Sables has grown into a family of events that test endurance in different ways, across different landscapes, and for very different runners. Yet the heart of MDS remains the same. Self-sufficiency, shared hardship, and the quiet satisfaction that comes from moving forward when stopping would be easier.

January opens with something new and bold: MDS Ultra. Two distances. Two very clear challenges. A 100km option for runners ready to push beyond the classic stage format, and a 100-mile race for those who want to see how deep the well really goes.

Photo by Ian Corless

An opening act designed to grab attention. Long distances, sustained effort, and the mental strain that only ultra racing can deliver. For many, it will be the first real test of their winter training. For others, it will be the centrepiece of their season. What matters most is what MDS Ultra represents – It signals evolution not revolution. MDS is not standing still, even as it celebrates its past.

Photo by Ian Corless

Before January ends, the focus shifts west to the ocean for MDS 120 Atlantic Coast. Where dunes once dominated the horizon, runners now deal with open beaches, shifting sand, and the constant presence of the sea. The Atlantic Coast event has its own rhythm. Wind can play a bigger role. Footing changes by the kilometre. Temperatures can vary greatly, and yes, rain may be present? Still self-supported, still demanding, but in a way that surprises many first-timers. By the time the final runners cross the line, January has already delivered two very different expressions of what Marathon des Sables can be.

February and March bring a noticeable change of pace. No race numbers. No finish lines. Instead, preparation. The MDS team turns its attention fully toward the centrepiece of the year: the 40th edition of MDS Legendary. Four decades after the first runners set off into the Sahara, this anniversary edition carries weight. Not just for the organisation, but for the community that has grown around it.

Photo by Ian Corless

Behind the scenes, logistics are refined, routes considered, and details checked and checked again. The Legendary event is not just another race, it is a reference point for stage racing, for many, a rites of passage, and in 2026, it will also be a celebration of everything Marathon des Sables has become.

Once the Legendary edition is complete, the calendar opens up again, and the global nature of MDS takes centre stage.

MDS Raid Namibia delivers raw beauty and isolation in one of Africa’s most striking landscapes. Namibia’s vast spaces, sharp light, and unforgiving terrain strip things back to basics. This is running in its purest form, where the environment sets the rules. A unique event as teams of two challenge a more stripped back and raw experience.

From Namibia, the series moves to Turkey for MDS 120 Cappadocia. Volcanic rock formations, flowing trails, and a sense of history underfoot make this one of the most visually distinctive events on the calendar. It is demanding, but also deeply immersive, ironically, despite the ‘sables’ tag, this event is much more a trail race – something new, different and unique.

MDS Crazy Loops – a format that lives up to its name. Short loops, repeated efforts, and a psychological game that can unravel even experienced runners over 24-hours. It is less about distance on paper and more about resilience in the moment. A fun and challenging event for all abilities that takes place at iconic ski resorts within Europe during July and August. A community event that brings the MDS vibe to the mountains.

As the year moves toward its final months, the pace does not slow. If anything, it accelerates. MDS 120 Morocco returns runners to familiar terrain, but with the confidence and refinement that come from years of experience. This is the desert, revisited with fresh eyes.

Alongside it, MDS Handi continues to redefine what inclusion looks like in endurance sport. It is a powerful reminder that challenge is not one-size-fits-all, and that determination takes many forms.

For those drawn more to movement than racing, MDS Trek Morocco offers a different relationship with the landscape. Still demanding, still immersive, but with space to absorb the experience in full where all abilities are catered for and yes, there is even some luxury – larger tents, no self-sufficiency, showers and so much more…

The international push continues with MDS 120 Jordan, where desert running meets ancient history. The terrain is tough, the scenery unforgettable, and the sense of scale impossible to ignore. An iconic event and arguably one of the most desired events on the MDS calendar.

And yes, there are hints of more to come. Potential surprises remain under wraps, but if past years are any guide, they will add another layer to an already remarkable season.

Photo by Ian Corless

By the time 2026 draws to a close, Marathon des Sables will have crossed continents and climates. Morocco, Jordan, Peru, Turkey, Namibia, and Europe, with the Alps adding altitude to the mix. Each location brings its own challenges, its own stories, and its own reasons for being unforgettable.

What ties them all together is not just branding or format. It is philosophy. Self-reliance. Respect for the environment. And the shared understanding among participants that this is about more than running.

A milestone year invites reflection, but it also demands momentum. In 2026, Marathon des Sables manages both. Honouring 40 years of history while pushing forward into new territory, new formats, and new ways to test human endurance.

For runners, supporters, and the wider endurance community, it is hard not to look at the year ahead and feel a quiet sense of anticipation.

What a year it promises to be.

In addition to the above, there is the MDS Tour and MDS Clubs.

MDS Legendary – 40th Edition To Feature Record Breaking Long Day!

Photo by Ian Corless

In 2026, the Marathon des Sables (MDS) reaches a milestone: its 40th “Legendary” edition. What better way to celebrate four decades of desert ultra-endurance than by rewriting the record books? Among the announcements already stirring excitement: the “long day” stage for 2026 will be extended to 100 km, making it the longest single stage ever in MDS history. This bold move not only raises the bar for what runners will face, but signals that the 40th edition aims to become a defining moment of the race’s legacy.

Laurence Klein, 3x MDS champion – Photo by Ian Corless

A Brief History:

The roots of the Marathon des Sables reach back to the daring vision of French promoter Patrick Bauer. In 1984, he traversed part of the Sahara on his own, over 350 km in 12 days, with no external support, an experiment in isolation and survival. Two years later, in 1986, the first official Marathon des Sables was held, with 23 participants tackling a self-supported desert crossing. The winners, Bernard Gaudin and Christiane Plumere making history.

Over the years, MDS has grown from a niche extreme-race to one of the world’s most respected ultramarathons. Its signature format currently features around 250 km over 6-stages (7-days) in the Moroccan Sahara, with participants carrying their own supplies (food, sleeping gear, etc.) in full self-sufficiency – water and a place to sleep the only logistical supply. Terrain at The Legendary shifts from endless dunes, rocky plateaus, dried wadis, occasional mountains and shifting sands; daytime heat can often soar, while nighttime temperatures can drop sharply. 

Stunning vistas at The Legendary – Photo by Ian Corless

Notably, throughout its history, MDS Legendary has always included a stage that stretches well beyond the “single marathon” distance, 80–90 km is normal to test endurance in extremes. In 2009, there was a long-stage of 92km’s…. But a full 100 km in one go will top them all.

With a passing of time, MDS Legendary has also diversified; now offering shorter formats such as MDS 120 (70–120 km), the MDS Trek variant with lighter logistics, MDS RAID and for 2026, the MDS Ultra which for the first time offers a single-stage ultra of 100km’s or 100-miles to be undertaken with a 40-hour cut-off. But the heart of the MDS  remains firmly with The Legendary stage race. 

The 100 km “Long Day” and What It Means

MDS will feature a 100 km long day, a stage longer than anything ever attempted in MDS history. This is more than a symbolic gesture, it’s a structural change that forces participants to rethink pacing, supplies, strategy, and mindset. Will the 40th edition of MDS The Legendary be considered the hardest ever edition? With an expected total distance of 270km +/- the answer is yes!

Photo by Ian Corless

From a participant perspective, there will be some key considerations.

  • Pacing will be crucial with a delicate balance between enthusiasm and energy conservation. During the day, monitoring thermal stress will be crucial.
  • Pack weight will be crucial – the 40th edition of MDS Legendary, now more than ever, will require participants to have the lightest possible pack without breaking the strict rules and regulations.
  • Food – With a long day that is in real terms approximately 10 to 25% longer than usual, the need for extra calories and how those calories are consumed will become extra important.
  • The mental toll will have a huge impact, that will start now with the announcement of a 100km stage – just as you prepare equipment and training, set time aside to prepare the mind for the challenge ahead. This new length will push athletes into deeper zones of fatigue, testing resilience, self-talk, and mental fortitude.
  • Runners will traverse more varied landscapes, perhaps crossing more dunes, rocky flats, and most certainly everyone will require more night navigation.
  • Announcing the 100 km day well in advance gives aspirants time to rework prep plans – use this time effectively.

Why 2026 Will Be a History-Making Edition

This is not just “another year” of MDS The Legendary, several factors are aligning to make the 40th edition uniquely compelling:

  • Milestone Significance – Forty years is a symbolic turning point. And by choosing to mark it with the toughest-ever stage, the organisers are intentionally raising the narrative: “Legendary by name, Legendary by reputation.”
  • New Records, New Legends – With no past precedent for a 100 km stage in MDS The Legendary, whoever finishes that leg (especially among the leaders) will enter the record books.
  • Attracting Ambition – Some ultra runners chase the “most difficult” challenge. A 100 km desert stage is a headline that will draw audacious minds and bodies, possibly pushing the field performance upward.
  • Legacy and Storytelling – In future retellings, the 2026 MDS The Legendary will be a pivotal point, some may say, the 40th edition was when MDS truly redefined itself. It’s the kind of turning point that historians of sport may hark back to.
  • Amplifying the Extremes – MDS has always lived on the edge: heat, sand, navigation, resource management. By stretching one day to 100 km, the extremity is amplified. The race becomes less about surviving the day, and more about mastering it.
  • The Longest Ever – With a long stage of 100km, the anticipated total distance for the 40th edition will be a record breaking 270km +/-.

Challenges & Risks to Keep in Mind

No radical shift comes without risks and MDS The Legendary are required to balance risk against challenge. A 100km stage has long been discussed for this iconic stage race, it’s only right that the 40th edition will personify the Legendary tag with a landmark distance. However, even the world’s top ultra runners may falter under a 100 km leg in desert conditions. Managing attrition will be critical. The required pace will be, as usual, 3.5km per-hour. And of course, the MDS blue and orange jackets will be on-hand, more than ever, to facilitate everyone crossing the line.

Some participants may feel disadvantaged if their prior prep or experience didn’t anticipate such a long stage, but, this is why this early announcement helps – fail to prepare, prepare to fail.

Perspective: How This Compares to Classic Ultra Benchmarks

To put 100 km in context: many stand-alone ultramarathons are in the 100 km to 100-mile range. But those are often supported events, with aid stations and crew support. In MDS The Legendary, with self-sufficiency, navigation demands, and desert extremes, layering a 100 km day is far harder than a flat 100k road ultra.

In prior MDS editions, long days of 80–90 km have already pushed runners to the brink, many cross the  nights and run long into another day – for 2026, this will be the ‘norm’ for nearly all the participants.

The 40th edition becomes not just “another chapter,” but a rewriting of what MDS can be.

Final Thoughts: A Legendary Promise

The 2026 Marathon des Sables is setting the stage, literally and metaphorically for a landmark event. The 100 km long day announcement signals ambition, courage, and a willingness to push the narrative frontier of desert ultra-running. In addition, the implications  for the overall race distance being 270k +/- adds to the drama.

For participants, 2026 will demand a rethinking of training philosophies, gear choices, pacing strategies, and mental frameworks. For the sport, it may become a reference point for what is “next level” in multi-stage desert ultras. And for storytelling, it offers rich stories:

“Who conquered 100 km in the sands?”

“How 2026 changed MDS forever.”

Legendary by name, and with this edition, legendary by reputation in a whole new way.

Countdown to MDS The Legendary 2025 – Issue One

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 : Podcast Two with Marie-Christine Barnett-Lonergan

Episode two of the Marathon des Sables – The Legendary podcast is with Marie-Christine (MC) Barnett-Lonergan.

Prepare yourself, this is quite a story from MC and one that I firmly believe will bring a tear to your eye.

Listen to the podcast on Apple HERE

Spotify HERE

When I reached out for MDS stories, I knew I would find some remarkable people and MC is most definitely remarkable.

“I am MC, a 37-year old mum of two. I’m a terrible runner and not an athlete. I have never done a half-marathon until late 2023. But I am doing MDS in April.”

It was one of those introductions that had me asking, why?

“In 2015 my mum suffered a very sudden and horrific illness which left her paralysed from the neck down and reliant on a ventilator to breathe. My mum is locked in her body and has little outdoor space, so, I am doing MDS to raise funds for the Royal Hospital for Neuro-disability”

But, the story does not stop there!

Listen to the podcast and be inspired.

If you would like to MC in her fund raising goals Royal Hospital for Neuro-disability Please go HERE.

“I am running to raise money to build a new and safe garden, where residents can sit independently and share time with their families. You don’t need me to tell you that being outdoors, surrounded by nature is so incredibly important to our mental health. This new garden will change lives (my mum’s, her fellow residents’ and all the families’) and take a huge pressure off the staff who so lovingly dedicate their lives to caring for others.”
