Grand Ridge Trail Run

The event is the final race of the Evergreen Trail Runs season and offers multiple distance options: a 5 mile course, a half marathon loop, a full marathon (two half loops) and a 50K (two half loops plus the 5 mile loop). The venue is Grand Ridge Park in the Cascade foothills near Issaquah, Washington. Trails pass through lush, rain-fed forest with fields of ferns and mossy trees showing fall colors.

The course is formed from two distinct loops. All distances start at the Highpoint Way Trailhead and follow the Issaquah-Preston Trail before climbing on rocky, technical switchbacks. The half loop measures closer to 14 miles than 13. Elevation gain is listed approximately as: 5 mile 1200 ft, half 2200 ft, full 4400 ft, 50K 5600 ft.

Aid stations are located at approximate mile markers and are stocked with water, Tailwind, Clif products, PBJ sandwiches, fruit, cookies, crackers and pretzels. The race is cupless; participants should carry a refillable container. Trails remain open to other users during the event including pedestrians and cyclists. Series awards are mailed the week after the race and every finisher receives a handmade piece of finisher swag produced with solar power.
