Ultra challenge des escaliers des dunes - Poitiers 2027

The Ultra Challenge des Escaliers des Dunes is an ultra-running trail event in Poitiers, France's Vienne department, scheduled for March, with the exact date to be confirmed. The format is straightforward yet demanding: runners select from 17.2 km, 34.4 km, or 68.8 km, with the climbing distances being the race's focus. The 17.2 km option is designated as a discovery trail and already includes over 2,500 meters of elevation gain. The 34.4 km short trail doubles that to over 5,000 meters, while the 68.8 km long trail exceeds 10,000 meters of gain and has an 11 p.m. cutoff. The organizer directs runners to a Facebook page for updates, which is important as the March date is not yet fixed.
