Roll out of Damazan and let the ride unfold along the Canal Latéral à la Garonne, then on beside the La Baïse and the La Gélise rivers. The Château de Barbaste and La Tour d'Avance castles break up the middle of the route before the road turns you back toward home. All told it's 70.0 km with 503 m of climbing, mostly on paved surface with a short unpaved stretch.
