A very long climb for the region. The first part is a long false flat climb, but it's not to be ignored as the westerly wind often blows hard across the fields. The steepest part begins at the hamlet of Le Rosnel and ends in the woods.... read more

A very long climb for the region. The first part is a long false flat climb, but it's not to be ignored as the westerly wind often blows hard across the fields. The steepest part begins at the hamlet of Le Rosnel and ends in the woods.

Ascension très longue pour la région. La première partie s'effectue sur un long faux plat montant mais elle n'est pas à négliger car le vent d'ouest souffle souvent et parfois fort au milieu des champs. La partie la plus raide commence au hameau du Rosnel et finit dans les bois.
