The Dirty Dozen - A Stupendous Bike Ride
Started in 1983, the Dirty Dozen showcases Pittsburgh’s steepest and toughest hills in one ride, often in freezing cold, wet and windy conditions. With 13 severe climbs ranging from 18 to 37% over more than 50 miles, the rules state you have to ride up every hill using your own power without stopping or crashing, with continuous forward motion up the hill. You can go back down to the bottom and try as many times as you like. The film highlights the 2010 event.
