Coming May 22, 2015. A weekend of pedaling fun! The Iron Horse Bicycle Classic in Durango, Colorado has something for everyone. What started out as a friendly sibling challenge with one brother on the train and the other on a ten-speed bicycle, attempting to to see who could travel the fastest from Durango to Silverton, has grown into criteriums, circuit races, road races, tours, BMX races, timed trials, dual slaloms, team trail rides, and mountain bike races. Whether you’re looking for a serious challenge or just a fun ride, sign up now since some of the events fill up quickly!
