Port de Larrau

Port de Larrau is one of cycling's great tests — 14.8km of sustained climbing, gaining 1,215m from base to summit. The average gradient of 8.2% disguises ramps of 18% — the kind of gradient that turns plans into prayers. 15 hairpins punctuate the ascent, offering brief respite in the corners before the gradient bites again. The road reaches 1,575m — high enough to feel the altitude on tired legs. Located in Navarre, France.
