Trail du Bois de Trémelin is a Sunday trail race in Inzinzac-Lochrist, in Brittany. Runners choose between two distances, 8 km and 16 km, which makes it open to both shorter-course trail runners and people wanting a longer local race.
The event draws close to 800 participants across the two courses and also counts toward the Challenge Bro an Oriant. On the 16 km race, Nathan Champion and Perle Champion, a couple, have both stood out as dominant winners.
