Brünn from Carrera

The Brün rises 6.5km through wooded valleys and open mountainside, gaining 675m to 1,580m. The average gradient of 10.3% disguises ramps of 27.3% — the kind of gradient that turns plans into prayers. 12 hairpins punctuate the ascent, offering brief respite in the corners before the gradient bites again. The road reaches 1,580m — high enough to feel the altitude on tired legs. Located in Grisons, Switzerland.
