The ride
Roll out of Najac and the castle is your send-off before the road drops toward the Aveyron river. From there the route keeps finding water, following the Viaur and the Cérou through the countryside. With 71.5 km and 1350 m of climbing, it's a steady day of ups and downs. The surface is almost entirely paved, and the loop brings you back to Najac.
