MorzineThe MDS Morzine 2026 will be taking place in the heart of the Alps for an exceptional event combining trail running, adventure and personal challenge. Inspired by the legendary Marathon des Sables, this event offers a unique format in the mountains, in the spectacular setting of Morzine and the Portes du Soleil.

A UNIQUE & INCLUSIVE MOUNTAIN CHALLENGE
24 hours of running, day and night, on loops of 3 to 5 km to be repeated freely.
Go at your own pace, solo or in a team, running or walking. One loop, ten, twenty… anything’s possible.
Experience ultra running in a different way: 3 to 5 disabled teams will share the course with you.
You can help them over a hill, accompany them on a technical section… here, everyone is a Helping Runner. No fixed role, just solidarity in action.
Each participant discovers that ultra is not just about performance, but also about helping each other, sharing and collective strength.
Morzine: an exceptional playground
Situated in the heart of the Alps, Morzine offers a spectacular natural setting: forests, mountain pastures and panoramic views of the peaks.
In summer, the resort becomes an outdoor hub: hiking, mountain biking, trail running, white water activities…
MDS Crazy Loops – Relive previous editions

THE CRAZY LOOPS SPIRIT
Here, ultra champions are not just those who run the fastest or the furthest. They’re also the ones we call “Handi”, for whom every daily effort is a victory.
Crazy Loops is :
-
A loop of 3 to 5 km to be repeated freely for 24 hours
-
Running, walking, pushing, pulling, stopping… and starting again
-
Celebrating, sharing a meal, exchanging glances
Here, we learn to see disability as a strength, to share, to create links and to leave with new encounters and a new impetus.
