Grand Ridge Trail Run

Grand Ridge Trail Run

Grand Ridge Trail Run is the final race of the Evergreen Trail Runs season, held at Grand Ridge Park near Issaquah, Washington on November 7, 2026. The event offers multiple distance options on a course made of two distinct loops: a dedicated 5-mile loop and a longer half-marathon loop that longer-distance entrants repeat as needed.

The distances:

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

All courses start from the Highpoint Way Trailhead and follow the Issaquah-Preston Trail for 0.5 miles before beginning a steep climb via rocky, technical switchbacks. Trails run through dense Cascade foothill forest with ferns, moss-covered trees, and fall colors. Trail surfaces are graded but include substantial climbing; approximate elevation gains are: 5 mile 1200 ft, half 2200 ft, full 4400 ft, 50K 5600 ft.

Aid stations are placed at approximate mile markers and are stocked with water, Tailwind, Clif product, PBJ sandwiches, fruit, cookies, crackers, and pretzels. This is a cupless race; participants should carry a refillable container as only a limited number of cups are available for emergencies. Trails remain open to other users during the event. The event includes a free Woodland Speeders kids race on a 1.1 mile crushed-gravel course with little elevation gain. Parking is available at the trailhead, along SE 79th St, and at a nearby church lot. Every finisher receives a handmade piece of finisher swag produced using solar power.
