The Experience
Starting from the Cocopah Casino & Resort in Somerton, Arizona, the Yuma Territorial Half Marathon takes runners on an out-and-back journey through the agricultural heart of the desert southwest. The course rolls gently through lettuce fields and the small town of Somerton, with the first two miles offering a favorable downhill start. Runners note a gradual uphill from mile 3 to the turnaround, but the return leg is predominantly downhill until a final climb back to the casino finish line.
The course is USATF certified and almost entirely flat, making it a prime candidate for personal bests and Boston Marathon qualifying. The small field and low-key atmosphere mean limited spectator support, but the race is well-organized with ample aid stations. Post-race, participants can enjoy the casino’s amenities, though the swag is minimal. With perfect January weather and easy parking at the on-site hotel, this half marathon is a hidden gem for runners seeking a fast, no-fuss desert race.
