Squak Mountain is arguably one of our most challenging trail races and a staff favorite! Trail distances include a 12K, half marathon and a 50K. There's even an option for the kids.

We’ve changed the course around a bit this year and we think you’ll like the differences. Instead of multiple confusing loops, we have simplified the courses. Although, it still isn’t super straight forward and while we mark our courses very well we encourage you to study the map before the event. Please see the color-coded map below for the order of trails in which you will run and email us if you have any questions.

All distances will begin with a steady but significant climb. The 12k will then split off from the Half course and head towards the summit aid station, while the Half and 50k runners will continue on up to summit the Southeast Peak of Squak. The Half course will then follow trails along the north side of Squak before arriving at the Summit Aid for the first time. Then after completing another loop using some of the Chybinski Loop and summiting the West Peak of Squak the Half course will pass by the Summit aid stations again. All distances will descend west past the old historic Bullitt homestead remnants.​ This trail is super fun, fast, and technical! While the Half and 12k runners will then be enjoying excellent post-race refreshments, the 50k runners will get to enjoy the Half loop again! Then after passing the lap aid station a second time they will head out again and do a 5 mile loop. It will travel the initial part of the first climb, cut west after 1000′ of gain, and link back up with the Bullitt Gorge Trail Descent all the way to a rewarding finish!

Race Notes

Squak Mountain is comprised of two courses: a 12K loop and a half-marathon loop. The 50K runners get to complete two half-marathon loops and a bonus 5-mile loop – lucky! Both courses start and finish at the main Squak Mountain Trailhead.

The trails will be open to other users during the event, including equestrians on the first small loop, and hikers. See our FAQ page for more information about sharing the trails.

There will be aid stations throughout the course with volunteers to help, food to eat and hydration to refuel. And of course, there will be an assortment of yummy food and treats waiting for you at the finish line.

This is a cupless race. All runners should carry with them a refillable container that they can run with. There will be a limited number of cups for emergency situations.

Squak Mountain is a Washington State Park, which means that a Discover Pass is needed to park. See the Directions section below for more information.
