About This Race
The 100K stands as the festival's ultimate test, demanding runners complete multiple loops through Fruita's challenging desert terrain while managing the complexities of nutrition, pacing, and mental fortitude across what typically becomes a 12-16 hour journey. This distance attracts experienced ultrarunners seeking a serious challenge that qualifies for Western States, requiring strategic loop management as the desert heat builds and the technical singletrack becomes increasingly demanding with each circuit. The extended time on course transforms familiar trail features into evolving obstacles, making this the choice for runners ready to push their limits while experiencing the full spectrum of high desert conditions from dawn through dusk.
