Tschiertschen from Chur

Tschiertschen from Chur is one of cycling's great tests — 16.7km of sustained climbing, gaining 1,419m from base to summit. The average gradient of 8.5% disguises ramps of 18.8% — the kind of gradient that turns plans into prayers. 13 hairpins punctuate the ascent, offering brief respite in the corners before the gradient bites again. The road reaches 1,974m — high enough to feel the altitude on tired legs. Located in Grisons, Switzerland.
