Nestled just a short drive from Seattle, Squak Mountain State Park offers an exhilarating trail running experience that feels worlds away from the city's hustle and bustle. This lush forest is home to steep terrain and endless shades of green, with moss-covered trees, ferns, and babbling streams providing both natural beauty and a welcome distraction as you tackle challenging climbs. The Squak Mountain Trail Race, organized by Evergreen Trail Runs, features distances that cater to all levels of runners but each includes significant elevation gain. The 12k begins alongside the Half Marathon route before veering off towards the summit aid station, while both half marathon and 50k participants continue on a more demanding path up Squak Mountain's Southeast Peak. For those tackling the half marathon or full 50k distance, the course offers varied terrain with technical trails that wind around the mountain’s peaks. After reaching the Summit Aid Station, runners will loop back using parts of the Chybinski Loop and summit West Peak before descending past remnants of the historic Bullitt homestead. The descent is a highlight for many runners, featuring fast-paced sections through dense forest. While half marathoners and 12k participants enjoy post-race refreshments at the finish line, those in the ultra-distance category get to experience this scenic trail one more time before heading back to the aid station. With its complex network of trails marked well but requiring careful navigation, studying a detailed map beforehand is highly recommended. The race celebrates nature and sustainability, embodying Evergreen Trail Runs’ commitment since 2010 under founders Roger Michel and Yumay Chang. Join Squak Mountain State Park on April 17, 2027 for an unforgettable trail running adventure that promises stunning views, challenging climbs, and a true wilderness experience.
