Grand Ridge Trail Run

Grand Ridge is the season finale of the Evergreen trail-running series, held at Grand Ridge Park in the Cascade foothills near Issaquah, Washington. The event offers multiple distance options:

  • 5 mile
  • Half marathon (approximately 14 miles)
  • Full marathon
  • 50K

All distances start from the Highpoint Way Trailhead and follow the Issaquah-Preston Trail for 0.5 miles before a climb. The course uses two distinct loops: a 5 mile loop and a longer half-marathon loop. Marathon participants run two half-marathon loops; 50K runners complete two half-marathon loops plus the 5 mile loop. Trails include rocky, technical switchbacks and varied climbing.

Aid stations are provided at approximate mile markers and 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. Trails remain open to other users during the event, including pedestrians and cyclists.

Elevation gain by distance is listed as: 5 mile 1,200 ft, half 2,200 ft, full 4,400 ft, 50K 5,600 ft. A 1.1 mile Woodland Speeders kid's race runs on crushed gravel with little elevation gain. Every finisher receives a handmade piece of finisher swag created with solar power. Series awards are mailed the week following the race. Parking is available at the trailhead and nearby lots.
