Roll out of Mussidan and the road leads you to the Château des Chauvaux, a castle on your way, before the Château de Mauriac brings another castle into view. The 80.0 km loop keeps you on paved surface the whole way, with 688 m of climbing to keep the legs interested. Follow the road down to L'Isle, where the river marks the turning point, then pedal back to Mussidan to close the circle.
