Castles between Tilly and Breuilpont

The ride

Roll out of Boisset-les-Prévanches and follow the Eure river before the Château de Breuilpont comes into view. Onward past the Château de Tilly and along La Vesgre to the Moulin des Osmeaux watermill, then beside La Blaise into the Forêt domaniale de Dreux. The Château de Fermaincourt rounds things off before the loop returns to the start village, all 81.2 km of it on paved surface.
