Prepare for a true test of grit and spirit at the Moscow Mountain Madness, an iconic Northwest trail tradition set for October 4, 2026, in the scenic hills above Moscow, Idaho. Offering challenging courses across 50K, 13.1M, and 5M distances, this race promises an unforgettable adventure along the rugged spine of Moscow Mountain. Runners will navigate mostly technical single-track trails interspersed with fast logging roads, experiencing "serious up, serious down, serious gorgeous" terrain and earning spectacular sweeping views of the Palouse region. The 50K, reinstated in 2024 after popular demand, provides an epic tour of the mountain's hidden gems, exploring vast trails that rarely repeat.

Since its inception in 1978, the Moscow Mountain Madness has earned a reputation for its demanding yet rewarding routes and lively atmosphere. Participants can expect frequent and well-supported aid stations, ensuring you stay fueled and hydrated on your journey. The half-marathon, for instance, features water stops at miles 5.5, 9.5, and 10.75, while the 5-mile course includes one at mile 3. Typical race day conditions in early October offer crisp autumn air, with highs around 67F and lows around 35F, and only a 9% chance of precipitation, perfect for trail running.

Whether you're tackling the 50K's 10-hour cut-off or embracing the scenic shorter distances, the Moscow Mountain Madness celebrates the "grit, challenge, and camaraderie" of the trail running community. With post-race food provided and a focus on experiencing the raw beauty of the Idaho backcountry, this event is a must for those craving a true mountain running experience.
