Les Douze Salopards
The Dirty Dozen was founded in 1983 by brothers Tom and Danny Chew and their friend Bob Gottlieb, in an attempt to find and ride the steepest hills in Pittsburgh. Five riders participated in the first edition, though only three finished. The race has been held every year since 1983—except 1993 and 2020. In 1984, the Dirty Dozen was contested twice: once in January and once in October.
