From Chanzeaux you roll out past the castle, then follow the Aubance out of the village. Two windmills mark the way before the route slips into the Loire-Anjou-Touraine nature reserve. The Layon and the Lys keep you company on the way back, with the castle of Gonnord along the ride. At 81.0 km and 98% paved, it's a loop that starts and finishes at home.
