Roll out of Saint-Pol-de-Léon and let the road carry you past the castle of Manoir de Kéroulas before the Penzé river joins the ride. Further on, the watermill of Moulin de Ramblouc'h and the castle of Manoir de Kersaliou mark the way, with the Guillec and L'Horn rivers slipping by in between. All 76.0 km are paved, and the route loops you back to where you started.
