24 Hours in the Old Pueblo
A lively celebration of mountain biking culture in Tucson's beautiful Sonoran Desert, 24 Hours in the Old Pueblo presented by Tucson Medical Center, is one of the largest 24-hour endurance events in the world. Going on two decades, this annual race around a single-track includes a bike expo, dedication dinner, late-night entertainment, and 24 hours of tunes provided by Tucsons 91.3FM KXCI Community Radio. Ride is limited to 1,400 and registration sells out. It's best to register well in advance.
