Roll out of Saint-Philbert-de-Grand-Lieu and let the ride unfold along the water. You follow the L'Ognon and then the Ilette, with the Sèvre Nantaise carrying you onward and the Maine rounding out the loop. The route runs 68.8 km with 338 m of climbing, almost all of it on paved surface. Four rivers, one start village, and a gentle return home.
