Cool Moon 100 Mile Endurance Run

About the event

Experience the breathtaking Cool Moon 100, an epic ultramarathon that winds through Northern California's stunning landscapes on June 12, 2027. This challenging course features two distinct loops: a 13.5-mile north loop and an 11.5-mile south loop, each brimming with rugged trails and scenic vistas. Runners will traverse the historic Western States trail, climb to K2's peak, and navigate single-track paths through backcountry terrain.
The route is meticulously marked for easy navigation as you ascend and descend over nearly 14,000 feet of elevation gain across the full distance. Aid stations are strategically placed along both loops, offering crucial support at critical points such as The Ranch and Cool Staging Area. With generous cut-off times extending to a total race window of up to 37 hours, this event is designed for endurance runners seeking a test of strength and resilience.
Upon crossing the finish line, participants will earn an exclusive silver buckle crafted by renowned silversmith James Stegman, alongside custom awards and swag. The Cool Moon 100 promises not only a physical challenge but also an immersive experience in one of California's most captivating natural settings.
