Roll out of Mondoubleau and let the ride unfold: past the river La Grenne, on to the castle at Saint-Agil, then along the Le Coëtron river and by the castle in Droué before the loop brings you home. Along the way you'll take in 503 m of climbing across 79.8 km, with the route almost entirely on paved surface. The castles and rivers come in a steady rhythm, and the road keeps turning back toward where you started.
