Roll out of Saint-Pierre-des-Corps and follow the water: first the river La Cisse, then Le Madelon and La Brenne, each one ticking by as the kilometres add up. Two castles break up the riding, Château de Montreuil and Château d'Amboise, before La Loire carries you toward home. The route runs 80.6 km with 377 m of climbing, and the surface is paved the whole way. Back to Saint-Pierre-des-Corps with river bends and castle walls behind you.
