La déferlante xtrem is a trail and walking series in Évreux, in the Eure department of Normandy, with its next edition planned for October, the exact day to be confirmed. The adult running options are short and approachable: an 8 km trail, a 12 km trail, and an 8 km night trail with over 130 meters of elevation gain.
The programme fits the “trail découverte” category, focusing on discovery-distance off-road running instead of long mountain-style racing. Families are included with a 2.5 km children’s trail and a Kids Fun and Sport event for ages 4 to 8. The walking options make it a broader outdoor event, not solely for runners.
