About the race
Snake Eater 100k is an ultramarathon in Grand Canyon, Tusayan, Arizona, offering 100K and 50K options. The course starts downtown Tusayan at the Grand Canyon National Park IMAX theater, then proceeds onto Fire Road 320, winding through forested terrain before connecting to the Arizona Trail and finishing back in Tusayan with about 30 miles of single-track. Runners tackle a rugged new trail system with stunning views of jagged peaks and expansive desert landscapes.
Presented by Bear Jaw Events, this adventure emphasizes endurance and exploration rather than speed. The race date is November 8, 2025, with permitting in progress and pre-registration open; final approval expected by October 1. Visit the organization's website for the most recent information.
