Staged on ~20-mile rolling singletrack anchored by the Pemberton Trail, the race uses festival vibes (“Jalloween”) to power a fast, looped course and big aid-station energy. The 100-mile covers five loops, the 100K three, and the 31K one, all from the Four Peaks Staging Area near Fountain Hills/Fort McDowell. It’s also a Western States Golden Ticket race, drawing deep competitive fields alongside costumed crews and runners. Expect exposed Sonoran-desert terrain, efficient logistics at “Javelina Jeadquarters,” and nonstop atmosphere all weekend.
