2014 Dirty Dozen

Every year, during the last weekend in November, the Dirty Dozen bike competition/event/whatever takes place in Pittsburgh, Pennsylvania. The Dirty Dozen started in 1983, and takes on 13 (a baker's dozen) of the city's steepest climbs, including what is arguably the steepest in the world, Canton Avenue.  Points are awarded to the first ten riders to make it up each of the climbs.
