Embark on an unforgettable trail running adventure with the Bigfoot 20 Mile Run on August 14, 2026, in Cougar, Washington. This challenging 20-mile race, known for its rigorous course, offers runners a unique journey through the breathtaking, untamed landscapes surrounding Mount St. Helens. Starting and finishing at Marble Mountain Sno-Park, the route plunges you directly into 100% single-track trails along the volcano's southwestern side.

Prepare to traverse diverse and demanding terrain, including ancient old-growth forests, thrilling stream crossings, and the striking, otherworldly expanse of lava and boulder fields born from the 1980 eruption. With a substantial 4,165 feet of elevation gain and 4,178 feet of loss, this race is far from a beginner's course, promising both physical and mental tests. Runners often praise the stunning scenery, calling Mount St. Helens "something to behold". Typical race day conditions in mid-August see comfortable highs around 80F and lows near 51F, with a minimal 3% chance of precipitation, providing generally favorable weather for mountain running.

Despite its remote mountain setting, the Bigfoot 20 Mile provides crucial support with one aid station at mile 12, stocked with ultra-distance essentials like sandwiches, fruit, soda, and gels. While there's no mandatory gear, participants are strongly encouraged to be self-sufficient and carry a jacket, extra layers, calories, and water. All finishers receive a unique, artist-made award, and a celebratory post-race meal awaits at the finish line. Free camping is available at Marble Mountain Sno-Park, allowing runners to fully immerse themselves in the Bigfoot experience.
