About the race
Squak Mountain Trail Run takes place at the May Valley Loop Trailhead in Squak Mountain State Park, just south of Issaquah, Washington. The course runs on forested, well‑maintained trails with moss, ferns, streams and glimpses of Issaquah and surrounding mountains.
All distances begin with a steady, significant climb and include rugged, steep and technical sections. The event uses three main loops: a 12K loop, a half‑marathon loop and a 50K loop; the 50K course repeats its loop to complete the distance. All routes descend past remnants of the historic Bullitt homestead. Aid stations are positioned on course with food and hydration; Evergreen Trail Runs operates a cupless policy so runners must carry a refillable container.
The half marathon is a points qualifier in the Vert Running Series. A free kids race is offered through the Woodland Speeders program; children’s distances vary and are approximately 1 km. Parking at the trailhead is very limited; a Discover Pass is required to park. Event registration is conditional on receiving a Special Use Permit from Washington State Parks.
