|The world of off-width crack climbing is a strange sub-culture rumored to be dominated by knuckle-dragging, bar-brawling dirt-bags! The climbing is tough, painful and bloody. Two climbers from England, Pete Whittaker and Tom Randall, set out to explore this world and climb the worlds hardest off-widths. They complete a brutal two-year training regime, mostly spent hanging upside down in a suburban Sheffield basement, before embarking on a tour of the USA. The tour culminates in the first ascent of the ultimate off-width test piece, Century Crack, the world's hardest off-width.
