MDS Crazy Loops Morzine

An exceptional event combining trail running, adventure and personal challenge, inspired by the legendary Marathon des Sables.

This unique challenge involves 24 hours of running - day and night - on loops of 3km to 5km, on repeat.

Go at your own pace as an individual, or in a team, running or walking - do one loop, 20, 40… whatever is possible. There will be three to five disabled teams sharing the course with you - you can help them over the hills, accompany them on a technical section, basically everyone here is a ‘helping runner’. No fixed role, just solidarity in action.
