Epouvant Trail is a Halloween night trail race in Valbonne, Alpes-Maritimes. Participants select either an 8 km or a 15 km route. The darkness is integral to the event; a headlamp is mandatory equipment.
The race begins at Bouillides, at La Source, on the west side of Parc des Bouillides. The 8 km course crosses the western section of Parc de la Brague. This is a local trail race focused on forest paths, night running, and a Halloween atmosphere, distinct from standard road races.
