Rondje Château de Carheil en Canal de Nantes à Brest

The ride

Roll out of Blain and the ride soon leaves the pavement behind, with most of the route running unpaved. The Isac river comes first, then the Canal de Nantes à Brest, both easy companions along the way. Later you pass the Château de Carheil, a castle that gives the middle of the loop its character. Then it's back to Blain to close the circle.
