This is one of the longer and more difficult climbs in the 7 Peaks. The roads are what we call “dead” in cycling lingo, as the surface is really slow. Many of the roads through the French Alps are made this way, making it hard to keep your momentum going. This means that every time you back off the pedals you come to a stop rather quickly.
With an average gradient of 6% and a distance of 45km this climb will take quite a while to complete, so it is important to eat and drink at regular intervals. Ideal places to do this are in the short downhill sections at the 10km, 17km and 26km points.
