Marmotte 4 – l’Alpe d’Huez

Almost a rite of passage for cyclists, the Alpe d’Huez climb begins after you descend the Col du Lautaret to Lac Chambon, make a small ascent, and traverse a stretch of valley floor. From there on, you dig deep –  really deep. Early sections of the climb have the steepest grades, but you need to push at full-throttle pretty much the whole way up. As you’ll see in the film, summer days find large numbers of cyclists taking the challenge.
