Roll out of Léognan and let the ride carry you past Château Belin, a castle on your way into the countryside. Next comes the Le Saucats river, then the Réserve naturelle géologique de Saucats et La Brède, a nature reserve where the route turns you back toward home. All told it's 79.9 km with 210 m of climbing, mostly paved with a short unpaved stretch. You finish where you started, in Léognan.
