Course Description
Runners start with a steady climb that sets the tone for the day—lungs pumping, legs firing. The 12K course branches off toward the summit before swooping back down, while the Half and 50K runners push farther up to conquer the Southeast Peak. The Half loops across ridges and summits the West Peak, while the 50K doubles down, adding extra loops for serious vert before circling back.
Highlights include sweeping summit views, the historic Bullitt homestead ruins, and plenty of rolling, rooty, technical singletrack that will keep you on your toes. Trails are well-marked, but with intersections throughout, studying the map before race day is a must.
Logistics
Seattle-Tacoma International Airport is the nearest major airport, located about 30 minutes from the race start in Issaquah, Washington.
Driving Directions
Parking
Parking is limited at the trailhead. 50K runners receive priority at the main lot. Additional parking is available on SE 135th St. in the Sunset Valley Farms neighborhood with a short walk to the start. Please stay on pavement when parking and avoid blocking driveways or parking on grass. Carpooling is strongly encouraged.
Passes Required
Lodging
Issaquah and the surrounding area offer plenty of lodging options, from hotels to short-term rentals. Nearby Seattle also has accommodations for those seeking a city stay before or after the race.
