Vallée d’Asco / Ascu Stagnu

The D47 rises 30.9km through rolling hills and mountain roads, gaining 1,223m to 1,422m. The average gradient of 4% disguises ramps of 10.1% — the kind of gradient that turns plans into prayers. This is a climb of endurance — the kind of effort measured in hours, where pacing matters more than power. Located in Corsica, France.
