Cool Moon Trail Runs

Embark on an unforgettable trail running adventure at the Cool Moon Trail Runs, taking place on June 14, 2026, in scenic Cool, California. This popular event, renowned for its welcoming atmosphere and meticulously marked trails, offers runners the choice of challenging 13.5-mile and 11.5-mile distances through the beautiful Auburn State Recreation Area. Typical race day conditions in mid-June feature average highs around 84°F and lows around 56°F, with a minimal 3% chance of precipitation, meaning runners should be prepared for warm, dry conditions.

The Cool Moon Trail Runs challenge participants with a unique course structure comprising two distinct loops: a 13.5-mile North loop and an 11.5-mile South loop. The North loop, considered more technical and exposed, features significant climbs, varied terrain, and approximately 2200 feet of elevation gain. Runners on this segment will traverse historic sections of the Western States trail, ascend the challenging "Pig Farm trail" to the top of K2, and navigate backcountry singletrack towards the American River. The slightly shorter 11.5-mile South loop, while more runnable, still presents engaging singletrack and mixed footing, winding through areas like Knickerbocker trail, Blue Oak trail, and the Rim Trail, with about 1150 feet of elevation change.

Runners consistently praise the event's exceptional organization and the course's clear markings, ensuring a smooth experience even amidst the challenging terrain. Aid stations, strategically placed every 2-5 miles, are fully stocked with water, Hammer Nutrition products, ice, soda, and a variety of snacks, providing crucial support throughout the race. The Cool Moon Trail Runs are celebrated for their inclusive, low-key vibe, making them ideal for both seasoned trail veterans seeking a rewarding challenge and those new to the sport looking for a well-supported and engaging race. All finishers receive a medal and shirt, with the start and finish line located at the accessible Cool Staging Area.
