Langs La Marsange en L'Yerres

The ride

Roll out of Verneuil-l'Étang and follow the route past the Ru de Bréon river, then on to the Château du Duc d'Epernon and the Château des Bisseaux. The road stays paved the whole way, with 342 m of climbing spread across the loop. Later you meet the L'Yerres and La Marsange rivers before turning back toward the start.
