Roll out of Bailly-Romainvilliers and let the route carry you from the Grand Morin river to the Marne, then along the Aqueduc de la Dhuis canal and past the Aubetin river before the loop brings you home. The 74.9 km runs entirely on paved surface, and with 468 m of climbing it keeps a gentle rhythm from start to finish. One village, four waterside and canal-side waypoints, and back where you began.
