2026 Grand Ridge Trail Run

Grand Ridge Regional Park sits just across I-90 from Tiger Mountain, a trail system east of Seattle that anchors one stop in the Evergreen Trail Runs series. This is dirt, not pavement — a half marathon run start to finish on trail.

Race morning is cool and damp, typically somewhere between the low 40s and mid 50s with humidity to match and a decent chance of rain. The route is well marked, and the half shares the day with everything from a 5-miler up to a 50K, so the field thins out quickly once the gun goes. Winning times around 1:47 suggest honest, runner-against-the-trail racing rather than a flat sprint.

Fields are modest: roughly 220 finishers at the median, closer to 190 recently, drawn from about a dozen states. What waits at the end is the series signature — a handmade wooden award and aid-station hospitality — rather than a stadium finish chute. It's a low-key Pacific Northwest trail day, and the kind of race that rewards simply showing up for the running.
