Rondje Château de Challain-la-Potherie en Forêt de Juigné

The ride

This loop sets off from La Chapelle-Glain and rolls through the Forêt de Juigné before following the La Verzée. Castles stack up along the way: Bois-Geslin, Challain-la-Potherie, La Saulaie and Bourmont, with the L'Argos and the L'Erdre flowing between them. At 76.9 km with 446 m of climbing, it's a steady day out, and the surface is almost entirely paved. You finish back where you started.
