24 Hours in the Old Pueblo (presented by TMC Health) is a 24-hour mountain bike race held February 12-14, 2027, over Presidents' Day weekend at 24 Hour Town on Willow Springs Ranch north of Tucson, Arizona. Riders race laps of a Sonoran Desert singletrack loop from a LeMans-style start at noon on Saturday, February 13, until noon on Sunday, either solo or on duo, 4-person, 5-person co-ed and corporate teams of 6-10 riders.
The 2027 edition marks 27 years of the event, which Epic Rides describes as one of the largest 24-hour races in the world. The 2027 field filled within a week of registration opening, and there is now a waitlist and a team/rider swap page. Entrants camp together in 24 Hour Town, which also hosts a bike and gear expo, food trucks, a beer garden and 24 hours of music from KXCI community radio. Camping passes go on sale November 1.
