Registration for Saguaro National Park Labor Day Run is closed. However, if you are registered, please click here for race weekend details, including packet pickup, race day schedules, and more. Old-timers will remember when this race was the Saguaro National Monument Run. In the last days of his presidency in 1933, Herbert Hoover established Saguaro National Monument, while it received National Park status in 1994. We are grateful to our friends at Saguaro for allowing us to be one of the few races produced on National Park lands. Park Ranger Steve Bolyard, Rincon Mountain District Ranger Miranda Cook, and Saguaro Chief Ranger Ray O'Neill have all provided above-and-beyond support for this race over the years. It takes a lot of folks to help with this race, so if you see a Park Service employee, please thank them for their efforts!
