The MDS Crazy Loops, a spin-off of the famous Marathon des Sables, stops in La Rosière for an extraordinary event. This immersive experience combines endurance, adventure, and a spirit of solidarity in an exceptional natural setting.
The course and activities are open to the public, offering a chance to explore the world of long-distance trail running and mountain racing.


It’s a total immersion in the spirit of adventure, where participants enjoy an intense experience in close contact with the mountains. The campsite, the camaraderie, and the shared effort create a unique atmosphere.
💡 The hotel’s tip: Plan to attend the mid-race events to experience the camp’s most immersive atmosphere and meet the riders when things are calmer and more accessible.
A memorable event—both athletic and community-oriented—that embodies the outdoor spirit of La Rosière.
