About This Race
The 100K serves as the premier Western States qualifier distance, demanding runners tackle the full spectrum of technical Sierra Nevada foothill terrain over 62 miles of challenging single track. This distance strikes the sweet spot for experienced ultrarunners seeking their first taste of Western States-caliber difficulty without committing to the full 100-mile distance, requiring sophisticated pacing and fueling strategies across the course's relentless climbs and descents. Golden Ticket opportunities for top finishers make this the most competitive distance at the event, attracting seasoned ultrarunners ready to prove themselves on terrain that will preview the demands of the Western States lottery system.
