The ride
Roll out of Allaire and let the route carry you past the river L'Oust, then on to the castle at Pordor. The Vilaine keeps you company before the Brière nature reserve opens up, and further along the castle of La Bretesche marks the way. It's 97.1 km with 799 m of climbing, all on paved surface, and it brings you back to Allaire.
