The Trail des Ayes begins in Toulaud, a village in Ardèche near Valence, using the stadium as its central point. This spring trail race offers two distances for adults: a 10 km with 400 m of elevation gain and a 22 km with 1000 m of elevation gain. Shorter races for children, 1 km and 2 km, take place in the afternoon before the adult events.
The adult courses start through Toulaud's streets before ascending to trails above the village. Participants will encounter forest paths, single-track sections, and sufficient elevation to ensure both distances provide a genuine trail running challenge. Portions of the course cross private property, meaning the precise routes and elevation profiles are disclosed only shortly before the event and again at bib collection. Now in its fourth year, the race saw over 600 participants in its last running. The local club also organizes regular runs on Wednesday evenings and Saturday mornings from the rugby stadium.
