Roll out of Quimper and let the route carry you along the Le Steir river, then the L'Odet, before the Le Steïr lake opens up beside you. Later the Manoir de Keramaner castle marks the way, and the loop brings you back to where you started. It's 68.5 km with 767 m of climbing, all of it on paved surface. A lively day that keeps unfolding from river to lake to castle and home again.
