The 10 steepest roads in the world

Ups that make you get off. You’ll need a compact chainset and a mountain bike cassette for these bad boys.

What classifies as a steep road is up for debate. The Guinness Book Of Records have their own classification (minimum length, straightness etc) but for the purposes of this round-up we’ve just concentrated on sheer gradient. Even if the road is not that steep for very long, we’ve still included it here.

Here are the top ten knee-snapping, lung-bleeding, mind-bending paved road climbs and their peak gradient percentages.


1. Bradford Street, San Francisco – 40%
