L'Epouvan'trail is a trail-running event in Sauvagnon, offering 10 km and 18 km routes. Both distances are run in a natural setting, emphasizing off-road running over city streets or track racing.
The program also includes a 10 km Canitrail, where runners and their dogs compete as a team. This marks the event's 17th edition, giving it established local history. The format remains straightforward: two trail distances for solo runners and a dog-friendly option focused on shared effort.
