Embark on an unforgettable trail running adventure at the Squak Mountain Trail Run, set for Saturday, April 18, 2026, in the stunning Squak Mountain State Park, Issaquah, WA. Choose your challenge from a 50K, Half Marathon (13.1M), or 12K, each offering a rigorous yet rewarding journey through the rugged and steep terrain of this Pacific Northwest gem. Known as one of the most challenging and beloved races by Evergreen Trail Runs, Squak Mountain promises significant climbs—up to 9,800 feet for the 50K—amidst a lush forest boasting every shade of green, moss-covered trees, ferns, and babbling streams. Despite its proximity to Seattle, the park offers a true wilderness solitude, providing breathtaking views and a course that is both technical and "super fun" on its downhill sections.

All distances kick off with a substantial ascent from the main Squak Mountain Trailhead, a hub for both start and finish lines. While the Half Marathon and 50K routes challenge runners with summits of the Southeast and West Peaks, the 50K includes additional loops to test endurance further. Aid stations are plentiful and strategically placed, with runners praising the friendly staff and "splendid" post-race refreshments. Expect typical race day conditions in mid-April with highs around 60F and lows around 43F, and a 12% chance of precipitation, meaning trails could be muddy and wet, adding to the adventurous spirit of the event.

The Squak Mountain Trail Run is lauded by participants for its challenging yet beautiful course, well-marked trails, and a wonderful community atmosphere, making it a favorite for those seeking a true test of their trail running prowess rather than a personal best. Be prepared to secure a Discover Pass for parking at the trailhead, though carpooling is highly encouraged due to limited space. This race is not just a run; it's an immersive experience in a treasured Washington State Park, leaving you with burning quads and lasting memories of its captivating beauty.
