La Vallon Trail is a small winter trail race held at Gymnase COSEC on Rue du Docteur Schweitzer in Avallon, Yonne department, Burgundy. CARTO organizes it in the Avallonnais region, offering two race options: a 10 km route and a 19 km route.
The 19 km race includes 720 metres of climbing, and the 10 km race has 350 metres of elevation gain, indicating it is not a flat course. Each distance is limited to 200 runners. The race starts in the afternoon and has age limits for participants, giving it the character of a local trail event rather than a large-scale competition.
