Course

All distances begin at the Highpoint Way Trailhead and follow the Issaquah-Preston Trail for 0.5 miles before a climb. The route includes rocky, technical switchbacks that lead to the 5-mile course junction. The 5-mile course forms a loop, while the longer distances follow a separate half-marathon-ish loop. Marathon runners complete two loops of the half-marathon route. 50K runners complete two half-marathon loops plus the 5-mile loop. The half-marathon loop is described as being closer to 14 miles than 13. The course passes the Flowing Fir Trail and the Duthie Aid Station and runs through dense, rainy forest with fields of ferns and mossy trees.
