In Valloire, at an altitude of 1,430 m, 18 km at an average gradient of 6.9% to the Col du Galibier await you, but as soon as you leave the village, a gradient of over 8% takes you to the hamlet of Les Verneys. A quieter 2 km brings you to the hamlet of Bonnenuit, where the climb continues to Plan Lachat and its short flat area. Once over the little bridge with its right-hand bend, there are 8 km to go at an average gradient of 8.5%, and the climb exceeds 2,000 m in altitude. You then enter a high mountain setting, and it's only three kilometers from the summit, on a small "flat spot", that you can see the summit of the Col du Galibier in the rocks. The pass in front of the tunnel (forbidden to bikes), at 2,556 m, almost heralds the end of the ascent, but with the last km at an average of 9%, the effort remains sustained all the way to the summit.
