Roll out of Cadillac-sur-Garonne and follow the Garonne river before the first castle of the day, Château de Saige, appears. Château d'Eyran and Château de Mongenan keep you company further along, with the Saucats river slipping in between. Later you pass Château de Portets, then track the Grand Estey and L'Œuille rivers on the way back. The full 78.3 km loop is entirely paved, with 409 m of climbing to keep the legs interested.
