Course and logistics
Courses start from the Highpoint Way Trailhead and follow the Issaquah-Preston Trail for 0.5 miles before a climb. Rocky, technical switchbacks lead to the 5-mile junction. The layout uses two distinct loops: a 5-mile loop and a half-marathon-ish loop (closer to 14 miles). Marathon runners complete two half loops; 50K runners complete two half loops plus the 5-mile loop. The route includes a detour on the Flowing Fir Trail and passes the Duthie aid station.
Elevation gain (approximate): 5 Mile 1200 ft; Half 2400 ft; Full 4800 ft; 50K 6000 ft. Aid stations are stocked with water, Tailwind, Clif products, PBJ sandwiches, fruit, cookies, crackers, and pretzels. This is a cupless event; runners should carry a refillable container. Trails remain open to other users, including pedestrians and cyclists. Youth and senior participants (22 and under or 65 and over) are eligible for a 15% registration discount.
