Trail de la Vallée de l'Yon 2026

The Trail de la Vallée de l'Yon is a trail running event held in mid-October in Rosnay, Vendée, western France. It offers several short-to-middle-distance options, ranging from 5.5 km to 32 km, alongside walking routes of 12 km and 20 km. The longer races feature significant local elevation gains: the 10 km has 197 m of ascent, the 17.5 km has 381 m, and the 32 km reaches 624 m. The 32 km is the most popular distance, and the previous edition saw over 100 participants. The courses traverse paths and trails through the Vendée bocage alongside the Yon river, passing through woods, meadows, and hillsides. A section also winds through the Rosnay vineyard area, part of the Fiefs Vendéens wine region. The event is organized by volunteers, maintaining a community atmosphere: all participants receive a memento, each race includes a prize draw, and one euro from each entry fee supports a humanitarian or charitable cause.
