Cool Moon 100 Mile Endurance Run

The Cool Moon 100 Mile Endurance Run is a challenging ultramarathon held in Cool, California. The race features a 100-mile course composed of four loops of two distinct trails: a 13.5-mile North loop and an 11.5-mile South loop, combining single track and fire roads with a total elevation gain of approximately 13,600 feet. The course is well-marked and includes multiple aid stations offering full support and water.

Runners have a generous 37-hour cutoff to complete the race and earn a unique silver finisher's buckle crafted by a renowned silversmith. The event offers live runner tracking and allows pacers after the third loop, with crew support limited to the start/finish area. Visit the organization's website for the most recent information.
