Grand Ridge Trail Run

Issaquah, United States • 7 Nov 2026

Grand Ridge Trail Run

Grand Ridge is the final race of the Evergreen Trail Runs season and offers multiple distance options: 5 Mile, Half Marathon, Full Marathon, and 50K.

  • 5 Mile
  • Half Marathon (approximately 14 miles)
  • Full Marathon (two half-marathon loops)
  • 50K (two half-marathon loops plus one 5-mile loop)

The event takes place at Grand Ridge Park in the Cascade foothills near Issaquah, Washington, with the race area at the Grand Ridge trailhead (27000 SE 79th St, Issaquah, WA). The park features connected trails through deep, rainy-forest habitat with fields of ferns, mossy trees, and fall colors.

The course uses two distinct loops. All distances start from the Highpoint Way Trailhead and follow the Issaquah-Preston Trail for 0.5 miles before a climb via rocky, technical switchbacks. The 5-mile course follows a lollipop loop; the longer distances continue along Grand Ridge, visit the Flowing Fir Trail, and pass the Duthie aid station. The half-marathon loop is closer to 14 miles than 13.

Elevation gain is substantial: 5 Mile 1200 ft, Half 2200 ft, Full 4400 ft, 50K 5600 ft. Aid stations provide water, Tailwind, Clif products, PBJ sandwiches, fruit, cookies, crackers and pretzels; volunteers assist at stations. This is a cupless race, so participants should carry a refillable container; a limited number of emergency cups will be available.

A free Woodland Speeders kid’s race runs on a crushed gravel 1.1-mile course with little elevation gain. Series awards are mailed the week following the race and finishers receive handmade swag produced with solar power. Visit the organization's website for the most recent information.
