Rondje Château du Guildo en Le Frémur

The ride

From Plévenon, this 70.0 km loop rolls out past the Le Frémur river and on to the L'Arguenon river before climbing its way to the Château du Guildo castle. With 691 m of elevation gain spread across the route, the ride keeps unfolding in gentle waves. The surface is 99% paved, with a small unpaved share along the way. Then it's back to Plévenon to close the loop.
