Climb Description

The Col de Marie Blanque is one of the more famous cycling climbs in this part of the Pyrenees. Its low altitude and friendly name belies a climb which is steep and challenging, and has destroyed many legs before they have even got the chance to tackle some of the higher climbs.

The Marie-Blanque has been used many times in the Tour de France, with the race climbing it from both sides. The climb usually comes early in a stage so it is rare for big names to lead the race over the top; however, the likes of Pedro Delgado, Luis Herrera and Richard Virenque have all crested the climb in first place.

This is the easier and also the more scenic side of the climb. There are several beautiful plateaus on the ascent, where the trees give way to offer stunning views across to the higher peaks of the Pyrenees.

The Marie-Blanque is open throughout the year.
