Rondje Château des Rohan en Le Blavet

The ride

Roll out of Bréhan and let the ride unfold along the water: first the Canal de Nantes à Brest, then its canalised L'Oust stretch, and on to the Le Blavet river. Midway the Château des Rohan castle gives the route its landmark moment before the Oust river carries you onward. All 79.6 km are paved, with 690 m of climbing to keep the legs honest, and the loop brings you back to Bréhan.
