Both the start and finish are at the Sky Country trailhead, accessed via 166th Way SE.

Course follows trails through Cougar Mountain Regional Wildland Park.

The route crosses fern-lined forest singletrack, climbs over hills and runs alongside wetland and marsh habitats.

The terrain is rolling, with several gradual climbs and a few short, steep ascents.

Total elevation gain is approximately 350 feet for 5km, 2,650 feet for 14.5 miles and 4,650 feet for 26.2 miles.

Course is marked on the trail and at every junction.

The series is designed to increase in distance from one race to the next, with the summer races held on the second Saturday of May, June, July and August.

August is the final race.

The 2026 event is the 23rd edition, and the series has donated more than $254,000 to King County Parks to date.

The 26.2-mile course records are 3:37:53 for men, set by Robert Orr in 2021, and 4:17:22 for women, set by Jenny Easterberg in 2017.

Since Old Man’s Trail near the finish was closed in 2019, approximately 65m has been added to each course.
