24 Hours in Old Pueblo

The eighth annual 24 Hours of Old Pueblo, one of the largest 24 hour races in North America, will happen February 17-18 north of Tucson, Arizona. Promoters attribute the race's popularity to its emphasis on celebrating mountain biking. Its late winter time slot also draws racers from colder climates looking for warmer weather.

"We like to think of the event as a huge party that happens to have a mountain bike race going on nearby," said Todd Sadow, president of Epic Rides, the promoting company. "The event has grown to attract more than 3,000 people, including participants and spectators, each year and that is a testament of its ability to appeal to a wide range of cyclists - not just the serious racers."
