La Barque Lait Jura 2027

La Barque Lait Jura is a 51 km nature trail race held in Bellegarde-sur-Valserine, within the Ain department of France’s Auvergne-Rhône-Alpes region. It takes place in late April and is not a straightforward solo daytime run: participants compete in teams, at night, over multiple days. The course follows a forest trail, with the primary environment being wooded terrain instead of city streets or track laps. The team format is significant, as the event emphasizes shared effort after dark, with runners spending extended periods together in the forest and covering the distance as a unit.
