Les nathurialaises - Saint-Thuriau 2027

Les Nathurialaises is a trail race held in Saint-Thuriau, Morbihan, near Pontivy. It offers three distances: 10 km, 16 km, and 26 km. The 10 km route involves approximately 150 meters of elevation gain, the 16 km route about 300 meters, and the 26 km route is listed with about 150 meters of gain. Sport Nature de Saint-Thuriau organizes the event, which includes official timing and aid stations along the course. The race succeeded the former Foulées de Saint-Thuriau and is now part of the Triskell Challenge trail series. It attracts a substantial field for a local trail race, with entries strong enough that additional bibs were provided after an initial sell-out. Registration can exceed 500 participants, partly due to a doctor's involvement in the organizing team. Participants must bring their own cups, as the event adheres to a zero-waste policy, providing no cups at aid stations.
