MDS Crazy Loops La Rosière 2026 - MARATHON DES SABLES

A unique challenge

The Inclusive Mountain Adventure

Forget the pressure of the clock, the fear of cut-off times, and the elitism of ultra-endurance.

THE CHALLENGE? An extraordinary adventure awaits you: run, walk, take a break, enjoy, start again… and complete as many loops as possible!

Everyone moves at their own pace, carried by the collective energy and the magic of the mountains. One loop, ten, twenty… anything is possible. You take part according to your wishes, solo or in a team, at your own rhythm, running or walking.

Experience ultra running in a whole new way

3 to 5 Handi teams will share the course with you. You'll cross paths with their determination, their smiles, and sometimes, you’ll even help them tackle a steep hill.

Everyone is a Helping Runner. On a tough climb, a tricky downhill, or just for the joy of it: you can join a Handi team at any moment and help them move forward.

No fixed roles, no rules: just solidarity in motion.

LA ROSIÈRE

A breathtaking playground

One of the most stunning natural backdrops in Europe: the French Alps. Here, everything feels more intense, more pure, more alive. From dramatic ridgelines to lush valleys, deep forests to sun-drenched alpine meadows, every square meter invites you to escape.

Perched at 1,850 meters of altitude, La Rosière offers a nonstop visual spectacle. Facing Mont Blanc and bathed in sunlight, this authentic mountain resort opens onto a 360° panorama between France and Italy. Breathing the Alpine air already makes you feel freer, lighter. Running through it... is a unique adventure, a timeless escape.

Here, nature is grand yet accessible. It welcomes athletes and dreamers alike—trail runners, wanderers, distance chasers, and partygoers seeking a different kind of weekend. It’s the perfect playground to run at your own pace, solo or with friends, in an atmosphere that’s festive, welcoming, and unmistakably Alpine.

You don’t come just to run. You come to feel, to share, to breathe, to laugh, and to reconnect with something essential.

THE CRAZY LOOPS SPIRIT

MDS Crazy Loops is where our differences draw the same path.

Here, the ultra-champions aren’t necessarily the fastest or those who go the furthest. They’re also the ones we call “Handi” — because for them, ultra is everyday life. Every movement is an effort. Every effort, a victory.

Crazy Loops is an experience to be lived together:

A 3 to 5 km loop, repeated freely
We run, we walk, we push, we pull, we stop... and we go again
We celebrate, we share a meal, we connect with a glance

Here, we learn to stop seeing disability as a weakness and start recognizing it as a strength that lifts us all. Come with your legs, your arms, your wheels, your doubts, your energy.

Leave with connections, stories, and sometimes, a new spark.

Build relationships

Crazy Loops isn’t a race. It’s a tribe.

A tented camp in the heart of the mountains, just like in the desert.

A space of freedom where roles fade, perspectives shift, and hearts open.

You give just as much as you receive.

And if you thought you knew what ultra meant, get ready to rediscover it. But in humanity.

Everyone is welcome

Your four-legged companions are welcome on-site and along the course.

Be sure to bring their essentials, such as water and food, so they can fully enjoy the adventure as well.

Please contact us if you wish to take part in the adventure with your pet, so that we can provide you with more details about the organization.
