Roll out of Bain-de-Bretagne and let the road carry you toward the water. You'll cross the Semnon and later the Brutz, two rivers that thread through this 80.0 km loop. Between them, the Étang de la Bornière opens up beside the route. With 576 m of climbing spread across the day, the pedals keep turning, and the ride brings you back to where you started.
