Trail des Petites Roches 2026

The Trail des Petites Roches takes place in early November in Saint-Hilaire, Isère, France, within the Auvergne-Rhône-Alpes region. It provides a 15 km option for those seeking a shorter mountain run and a 35 km route for participants desiring a more challenging day over technical terrain. The race's slogan, “a rocky trail, but not only,” accurately describes an event featuring forest paths, waterfalls, ascents, and uneven sections. The 15 km course winds through thick woodland and alongside waterfalls, offering a natural environment without the extended distance. The 35 km version includes strenuous climbs and difficult descents, and is also available as a team relay. The race highlights its local landscape: rocks are integral to its character, forests define the route, and the waterfall segments distinguish it from a standard trail race.
