About the climb

This climb sits in the Oisans, in the Isère part of the French Alps. It starts on the valley floor at Le Bourg-d'Oisans (722 m) and finishes in the ski resort at 1821 m: 13.9 km and 1109 m of climbing, at 7.9% on average.

The first kilometre is flat, so the climb proper is about 12.9 km long. It opens with its hardest stretch: kilometres 1 to 3.5 run at 9 to 12%, and a short easier 500 m at about 5% around 3.5 km is the only real breather. After that the profile is remarkably regular, with almost every 500 m between 7 and 10% all the way up. The last steep pitch comes at 13 km, at about 11%, before the road flattens for the final few hundred metres. The steepest 200 m on our track reaches 14.4%.

Pacing tip: the calculator puts a 75 kg rider at 3.0 W/kg on 1 h 16 min. Do not spend too much on the steep first 3.5 km: the next nine kilometres reward a power you can hold without change.
