La Douze

An innovative 12-hour trail in which each person creates his or her own race: freely link up different routes to accumulate points, solo or in relays, in an exceptional natural setting facing Mont Blanc.
La Douze - Mont-Blanc Passy is an original trail concept that turns traditional running codes on their head. There's no set distance: each participant creates his or her own 12-hour challenge, freely linking together several trails of varying distances and levels.

Accessible to all, from beginners to experienced trail runners, the event offers different loop formats (short to long, with progressive gradients) to be combined according to one's mood, current form or race strategy.

The objective is simple: to cover the greatest possible distance in the allotted time, accumulating points based on kilometers covered, positive elevation gain and bonus challenges along the way. But be careful with time management: any minute over the 12-hour time limit will result in penalties.

The event can be run solo or in relay (teams of 2 to 4 people), reinforcing the spirit of sharing and strategy. Everyone is free to alternate effort, recovery and conviviality in the race village.

Held at Passy Plaine-Joux, facing the Mont-Blanc massif, La Douze offers a unique immersion in the heart of nature, between forests, mountain pastures and exceptional panoramas. The event is as much about sport as it is about fun, with a convivial atmosphere and a collective closing ceremony for all participants.
