The Randonnée des Trois Vallées is a mountain bike and walking event held in Bessé-sur-Braye, Sarthe, France. The cycling component, known as VTT (off-road mountain biking), offers three route options: 25 km and 35 km marked as easy, and a more challenging 45 km route.
Walkers can choose from 10 km, 15 km, and 20 km routes. ANILLE BRAYE CYCLO is the organizing club, giving the event the feel of a local club ride rather than a competitive race focused on rankings or elite participants.
