Grand Ridge Trail Run

Grand Ridge Trail Run takes place on November 7, 2026, as the final event of the Evergreen Trail Runs season and serves as the series awards finale. Distances offered include:

  • 5 Mile
  • Half Marathon
  • Full Marathon
  • 50K

The event uses Grand Ridge Park in the Cascade foothills near Issaquah, Washington. Trails were developed by the Washington Trails Association and pass through dense, rainy forests with fields of ferns, mossy trees, and fall colors. The course layout consists of two distinct loops: a 5-mile loop and a longer half-marathonish loop closer to 14 miles. Marathon runners complete two half loops; 50K runners complete two half loops plus one 5-mile loop. All courses begin at the Highpoint Way Trailhead and follow the Issaquah-Preston Trail for 0.5 miles before climbing on rocky, technical switchbacks. The longer course detours onto the Flowing Fir Trail and passes the Duthie aid station.

Aid stations are stocked with water, Tailwind, Clif products, PBJ sandwiches, fruit, cookies, crackers, and pretzels. This is a cupless race; participants should carry a refillable container as cups are limited. Trails remain open to other users during the event.

Additional details: the race location is 27000 SE 79th St, Issaquah, WA. Elevation gain by distance is approximately 1200 ft for 5 mile, 2200 ft for half, 4400 ft for full, and 5600 ft for 50K. A free Woodland Speeders kids race uses a crushed gravel 1.1 mile course with little elevation gain. The race includes handmade finisher swag and acknowledges the Indigenous land of Coast Salish peoples, specifically the Snoqualmie Indian Tribe.
