The ride
Roll out of Sixt-sur-Aff and the route soon picks up the Canal de Nantes à Brest along the Oust Canalisé, then follows the Oust and the Arz rivers before meeting the Aff. The 65.3 km loop climbs for 769 m, with most of the riding on unpaved surface. Rivers keep you company in riding order, and the Aff leads you back toward Sixt-sur-Aff.
