Ride distance: 54km / 34mi

The cycling route we have mapped out below starts and finishes in the town of Saint Girons. The climb of the Col de la Crouzette is tackled from the southern approach via the small village of Biert. It is possible however to route yourself in a clockwise direction instead and to ride the climb from the northern approach of Riverenet. If you do this be mindful of the descent from the top of the Col de la Crouzette to Biert as the road is extremely steep and narrow.
