Prepare for an unforgettable challenge at the Squak Mountain race, set for April 18, 2026, in the lush wilderness of Issaquah, WA. This highly-regarded event, a staff favorite from Evergreen Trail Runs, offers a demanding yet rewarding experience across 50K, Half Marathon, and 12K distances. Runners will navigate rugged, steep terrain, beginning with a significant climb that immediately tests the quads. The course winds through a vibrant, moss-covered forest, adorned with ferns and babbling streams, providing a sense of solitude just a short drive from Seattle. With typical race day conditions seeing highs around 60F and lows near 43F, and only a 12% chance of precipitation, runners can expect cool, potentially misty, but generally favorable running weather.

The Squak Mountain courses are celebrated for their intricate network of well-maintained trails, delivering both breathtaking views of the surrounding mountains and glimpses of Issaquah below. Expect substantial elevation gain—the Half Marathon features approximately 4,100 feet of climbing, while the 50K pushes athletes with around 9,800 feet of ascent. Runners consistently praise the technical descents and the overall difficulty, making it an ideal race for those seeking a true test of grit and endurance. Aid stations are strategically placed, including a summit aid station visited multiple times for longer distances, though participants should note this is a cupless race requiring personal refillable containers.

Starting and finishing at the main Squak Mountain Trailhead, the event fosters a low-key, community-focused atmosphere that runners appreciate. Post-race, enjoy excellent refreshments and the satisfaction of conquering one of the region's most challenging trail races. Finishers are also awarded unique, handmade wooden awards, a special touch from the organizers. Whether you're aiming for a new distance or a challenging training run, Squak Mountain promises an exhilarating journey through the stunning Pacific Northwest.
