Roll out of Étampes and let the ride unfold: past the Palais de Justice castle, then along the Chalouette and Louette rivers before the route opens into the Gâtinais français nature reserve. Most of the 57.9 km runs unpaved, with 368 m of climbing spread across the loop. The Juine river escorts you on the way back, and the ride finishes where it began, in Étampes.
