Entrainement VTT 60Km

60km 700m D+ the last 15 km are on the road. The end of the Couesnon valley should be avoided (stairs) by following the stars on the map.

Starting from Saint Sulpice, head northeast to reach Gosné, then we connect with the forest of Saint Aubin and there we meet the GR39 variant heading towards the Couesnon valley which we traverse from east to west, changing banks at the D102 crossing.

To avoid the stairs in the far west part, we can exit at La Menotière (see map) and reconnect to the route a few hundred meters farther northwest. We then arrive at Vieux Vy sur Couesnon then Sens de Bretagne, and then reach Endouillé Neuville and Chasné via small roads (except the D106 before Chasné).
