La Jasseronnaise - ND2BR - 42 km 2026

La Jasseronnai'se Trails is a trail-running event in Jasseron, with races on paths and trails rather than roads. The program offers a 9 km route for people trying trail running, a 20 km race, and a 42 km option that can also be shared as a relay by two or three runners. The relay is capped at 40 teams, so the longest race keeps a small-team feel instead of turning into a huge field. The shorter course is called L'etang and is built as an accessible introduction to the local trails. The middle-distance route, Le Chateau, is aimed at runners who train regularly and includes more than 720 meters of climbing, taking the race onto the heights above Jasseron. The event already has several editions behind it, and its results are published online. It also supports Les p'tits doudous bressans, with runners, volunteers, and participants helping fund a donation to the charity.
