Embark on an unforgettable trail running adventure at the Cool Moon Trail Races, held on June 13, 2026, in scenic Cool, CA. This event caters to a wide range of runners, offering distances including 100K, 50M, 25M, 13.5M, 11.5M, and a 5K, all starting from the easily accessible Cool Staging Area. Runners will navigate a well-marked course consisting primarily of challenging single track and fire roads through the stunning Auburn State Recreation Area. The route features two distinct loops: a 13.5-mile North loop, known for its technical terrain and significant climbs like Pig Farm Trail (also called "Training Hill") and the Old Dam switchbacks, and an 11.5-mile South loop, which is generally more runnable through the golden hills. Expect substantial elevation gains, with the 100K boasting approximately 9,000 feet.

The Cool Moon Trail Races are celebrated for their exceptional organization and runner-friendly atmosphere, making it a "welcoming, low-key, and intentionally built to support runners of all backgrounds and paces". The unique alternating loop course design allows crews to easily access runners at the Cool Staging Area after each loop, a feature frequently praised by participants, especially for the longer distances. Aid stations are strategically placed every 2-5 miles, offering a generous spread of water, Hammer Nutrition, ice, soda, snacks, and other trail staples to keep you fueled. Typical race day conditions in mid-June bring highs around 84F and lows around 56F, with a minimal 3% chance of precipitation, suggesting warm but generally dry running.

While challenging, with some runners experiencing "Hellish heat & hills," the generous cutoffs for most distances ensure a supportive environment for achieving your goals. All finishers receive a commemorative medal and shirt, with 50-mile finishers earning a custom plaque and 100K finishers receiving a custom buckle, providing a well-deserved reward for your efforts on these demanding yet beautiful trails.
