Great hike, pretty easy overall. There are 3 small, old difficulties on the Orléans road, cobblestones in all directions and some brambles. The climb to the church of Saint Yon, and the climb along the Bois des Roches path towards the naturist camp also have cobblestones! Well, there's also the 80 km distance. No GPS needed for the last few kilometers.

Be careful if you plan to do this route on gravel. The single tracks in the forest are very mountain bike-style. There are some sections where the path is cut by tree trunks.
