About This Race
The 50K extends beyond the 30K's single loop experience, requiring runners to tackle the high desert terrain for additional miles that test both physical endurance and mental resilience in the exposed landscape. This distance appeals to experienced ultrarunners seeking a substantial challenge without the extreme commitment of longer formats, demanding careful pacing and nutrition strategies as the desert conditions amplify over the extended time on course. The additional mileage transforms the experience from a challenging trail run into a true ultra endurance test where the high desert's unforgiving elements become as much of an opponent as the distance itself.
Both the 50K and 30K follow loop courses on rolling dirt roads through classic Mojave Desert terrain. The courses climb and descend between 2,400 and 3,500 feet elevation, providing sustained but manageable challenges without technical trail obstacles. The desert setting offers expansive views and in December often features surprising displays of green vegetation and blooming wildflowers following winter rains.
Nine aid stations are positioned strategically throughout both courses, with key checkpoints including Gracie's aid station at 24.8 miles on the 50K and 15.1 miles on the 30K. The dirt road surface provides good footing year-round while maintaining the authentic desert trail experience that has drawn runners to this event for nearly four decades.

Notable Features
This race distinguishes itself through nearly four decades of consistent organization by a dedicated running club that reinvests proceeds into local youth programs. The December timing transforms the typically harsh Mojave Desert into a surprisingly green and flower-filled landscape, while the dirt road format makes it accessible to runners who might find technical singletrack intimidating. The race maintains old-school ultra values with generous cutoff times, comprehensive aid station support, and a genuine community atmosphere that has attracted repeat participants for decades.
