Yuma Territorial Marathon

The Yuma Territorial Marathon, held in Somerton, Arizona, is a USATF-certified race offering full marathon, half marathon, 10K, and team relay events. Starting and finishing at the Cocopah Casino & Resort, the course runs along the southbound shoulder of US Highway 95, passing through scenic desert landscapes and rural communities including Somerton, Gadsden, and San Luis. The mostly flat, out-and-back route features minimal elevation changes, with a slight downhill start and a gentle uphill near the finish, making it ideal for personal bests and Boston Marathon qualification.

Participants receive technical shirts, finisher medals, and cash prizes are awarded to top finishers. Visit the organization's website for the most recent information.
