The Trail de la Vallée de l'Ouche is a trail-running event held in Saint-Victor-sur-Ouche. It offers races from a 500 m children's run up to a 42 km Maratrail featuring 2,000 m of elevation gain. The event is designed for various skill levels, not just a single distance, with marked paths and aid stations along the routes.
The 14 km and 29 km races contribute to the Ouche et Montagne challenge, providing an incentive for participants aiming for that series. The event also benefits the association Partage and its humanitarian project, connecting the weekend to a local charity cause.
