Grand Ridge Trail Run : Event overview

The Grand Ridge Trail Run takes place on November 8, 2025, at Grand Ridge Regional Park in Issaquah, Washington (27000 SE 79th St). It is the Evergreen series finale and offers multiple distance options:

  • 5 Mile
  • Half Marathon (course described as closer to 14 miles)
  • Full Marathon (two half-marathon loops)
  • 50K (two half-marathon loops plus the 5-mile loop)

Every finisher receives a piece of handmade finisher swag produced with solar power in Anacortes. The event includes a free Woodland Speeders kid’s race on a crushed gravel, 1.1-mile course with little elevation gain. Post-race food includes hot meatballs with vegan options.

Course, aid stations, and logistics

All distances start at the Highpoint Way Trailhead and follow the Issaquah-Preston Trail for 0.5 miles before a climb. The course uses two distinct loops: a separate 5-mile loop and a longer half-marathon loop. Rocky, technical switchbacks lead to the 5-mile junction; the half/full/50K course includes a detour to the Flowing Fir Trail and reaches the Duthie aid station. Elevation gain is listed as: 5 mile 1200 ft, half 2400 ft, full 4800 ft, 50K 6000 ft. Aid stations provide water, Tailwind, Clif products, PBJ sandwiches, fruit, cookies, crackers and pretzels. The race is cupless : runners should carry a refillable container. Trails remain open to other users, including pedestrians and cyclists. Parking options are the small lot at the trailhead, roadside on SE 79th St, or the I-90 Church lot. Visit the organization's website for the most recent information.
