Stories, information and comments from Col du Buis climbers

I rode the Col du Buis from La Serre, ponte. Although the distance is relatively short (only 4 kilometers), this col is extremely difficult. Parts of the climb goes up to 18-20%. I experienced more difficulties than climbing for instance the Mont Ventoux.
