The Trail de Dieulefit begins in the town center, directly before the town hall, with all participants starting simultaneously at 9:00. The routes diverge within the forest shortly after the start. This April trail-running event in Dieulefit offers three challenging courses on technical, wooded paths: Le Mielleuse covers 10.6 km with 440 m of elevation gain, La Rachas Express spans 20.5 km with 900 m, and Les Ventes Folles extends 30.8 km with 1,460 m.
The shortest course provides a solid physical challenge, while the two longer distances are designed for those seeking continuous ascents and a demanding trail experience. The finish line is located at the Dieulefit gymnasium, where participants reunite with family and friends for a post-race buffet. The event also features the COURSETON children's races, with a 1.5 km distance for participants under 10 and a 3 km course for those aged 11 to 15; parents have the option to run with their children. Now in its ninth edition, the race has established itself as a local trail tradition rather than a singular mountain event.
