Evergreen Trail Runs · May Valley Loop Trailhead
Beautiful forested park in the Pacific Northwest features miles of trails in wilderness solitude with glimpses of Issaquah below
Breathtaking. Both kinds.
Squak Mountain is arguably one of our most challenging trail races and a staff favorite! We've changed the course around a bit this year, and we think you'll like the differences. The rugged, steep terrain of Squak Mountain is waiting for you! You'll find every shade of green imaginable in this lush forest. You can focus on the moss-covered trees, ferns, and babbling streams to distract you from those burning quads.
Squak Mountain will take your breath away – both the views and the elevation gain! It's not our steepest climb, but your quads will get a good workout, and it will be worth every step! While only a short drive from Seattle, Squak Mountain State Park feels like a wilderness solitude. The park features miles of well-maintained trails and beautiful views of the surrounding mountains.
Want to race but can’t afford the entry fee? The Trail Mix Fund can help.
Every distance starts with a steady, significant climb, and the longer courses summit Squak's peaks. Quiet forest, big vert, and hard-earned glimpses of Issaquah below.
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. All distances will descend west past the old historic Bullitt homestead remnants. This trail is super fun, fast, and technical!
Elevation gain: 2000′ (approximate).
All distances will begin with a steady but significant climb. 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 Station for the first time. Then complete another loop, using some of the Chybinski Loop, and summit the west peak of Squak. All distances will descend west past the old historic Bullitt homestead remnants. This trail is super fun, fast, and technical!
Elevation gain: 3800′ (approximate).
All distances will begin with a steady but significant climb. The Half and 50k runners will continue on up to summit the southeast peak of Squak. The 50K runners get to complete their loop twice! All distances will descend west past the old historic Bullitt homestead remnants. This trail is super fun, fast, and technical!
Elevation gain: 8800′ (approximate).
As part of our Woodland Speeders program, we offer free kid’s races at all of our events. Parents are welcome to run with their kiddos. You can register your child during the registration process for your own race, or sign them up later. Distances vary and are approximate, but we aim for about 1K in distance. See the schedule for start time.
The course at Squak is a fun interpretive nature loop with good singletrack, flat, and is 0.5 miles long.
Online registration will close the Friday before the race at noon.

Brunch Run entries cost the same as their distance. Kid's races are free. Taxes and fees are added at checkout.
Participants 22 and under or 65 and over can receive a discount of 15% on their registration fee. Request it with the discount form.
No. Almost all race costs are paid before race day and cannot be recovered, so entries are non-refundable. The one exception is the optional Refund Guarantee, below.
If you can't run, you have three options, each of which must be requested by 6:00pm the day before the race: transfer to another Evergreen Trail Runs event in the same year, defer to the same race next year, or give your bib to another runner. An entry can be deferred or transferred only once, and free entries that have been deferred or transferred are not eligible for a voucher. Cancelled or postponed races are not eligible for refunds.
Optional refund protection you can buy through Ultrasignup when you register. It is run entirely by Ultrasignup. With it, you can cancel up to 24 hours before the first start of the day (not your own distance's start) and receive an 80% refund from Ultrasignup, using the email they send you after registration.
Yes, until 6:00pm the day before the race. In your Ultrasignup account, choose race credit: you receive a credit worth 95% of your registration fee, good for any Evergreen Trail Runs race with open registration. If the new race costs less, the difference is not refunded. Transfers between Evergreen Trail Runs and Orca Running races are not possible, and an entry can be transferred only once.
Yes, until 6:00pm the day before the race, through your Ultrasignup account. The deferral fee is 5% of the registration fee. Once deferred, it is up to you to re-register for next year's race; if you have not applied the deferral by the time registration closes or the race sells out, it is void. An entry can be deferred only once.
Yes. Before registration closes, change it in your Ultrasignup account; after that, in person at packet pickup. Moving to a longer distance costs the difference in entry fee; moving to a shorter one is free but the difference is not refunded.
Please tell us before you switch. Running a different distance than the one you are registered for scrambles the results and delays the awards.
Yes. Bib transfers to another runner for the same race can be done online until registration closes, and after that in person at packet pickup or on race morning.
You can defer to the following year at no cost, or receive a refund. Contact us with proof of pregnancy before the normal deferral deadline.
Parents can ask for an exception by emailing info@evergreentrailruns.com at least five days before race day with a short note on the child's trail running experience.
Yes: runners 22 and under or 65 and over get 15% off the registration fee. Use the discount form linked on this page.
Overall winners are scored by gun time (clock time): the first three runners of each gender across the finish line, regardless of when they crossed the start. If the race starts in waves and you think you might place, start in the first wave, near the front, and answer the estimated-finish-time question at registration honestly.
No timing system is perfect. Wear your bib visibly on the front of your outermost layer. In some cases we can issue a gun time but not a chip time. Personal GPS data can help us investigate a result but is never the sole basis for an official one. Awards are collected at the race; we do not mail them.
Yes, since 2023. When you register you can choose male, female, non-binary, or prefer not to say. There are overall awards for the top three non-binary runners in every race, collected at the Evergreen tent. Choose prefer not to say if you would rather not be eligible for overall awards.
We only cancel when the safety risk is real: extreme heat or cold, hazardous air, unexpected trail closures, dangerous animals on the course, and the like. Whenever possible we postpone rather than cancel. If a race is postponed and you cannot make the new date, you can defer to next year for free, or transfer to another Evergreen Trail Runs event that year for a reduced fee of $5. Cancelled or postponed races are not eligible for refunds. We will do our best to reach every registered runner as early as we can.
Dogs are welcome at the start and finish area, but not on the course.
The full race policies are the final word on all of this.
Where: May Valley Loop Trailhead
There is very limited parking! Please carpool! The 50K runners will receive priority to park at the Squak Mountain/May Valley Loop trailhead.
When the lot fills up, please park on S.E. 135th St. in the Sunset Valley Farms neighborhood and walk to the start/finish. Do NOT park on May Valley Rd. Please stay on the pavement when you park in this neighborhood, not on the grass near the roadside ditch.
Please note that you will need a Discover Pass to park. To purchase, visit www.discoverpass.wa.gov.
Give yourself ample time to get to the race, pick up your bib, and get to the start line.
A Discover Pass is required to park.
The park is located just south of Issaquah, Washington.
From I-90, take exit 17. Head south on Front Street, which turns into Issaquah-Hobart Road. Drive 4.5 miles, then turn right on S.E. May Valley Road. Drive 1.5 miles and turn right into the park. If the lot is full, please park on nearby S.E. 135th St. Do NOT park on May Valley Rd.
There are three loops in this event: a 12K loop, a half-marathon loop, and a 50K loop. The 50K runners get to complete their loop twice! – lucky! Both courses start and finish at the May Valley Loop Trailhead.
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 Station for the first time. Then complete another loop, using some of the Chybinski Loop, and summit the west peak of Squak. The 50k has some extra loops built into this section before both the Half and 50k rejoin to head back to the Summit Aid Station. 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 enjoy excellent post-race refreshments, the 50K runners will get to enjoy their loop again!
While we mark our courses very well, this is a complex trail network with lots of intersections. 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.
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.

Squak was formed on the idea of providing reliable, readily available, and functional outdoor goods without charging extra simply for the name-brand. All participants receive a discount on their own Squak.

Evergreen Trails is proud to have Tailwind Hydration as our official hydration sponsor.
We partner with Trees not Tees, so you can have a tree planted instead of taking a race shirt you may never wear. Every event is planned to keep our footprint small. Read more.
There is space for all on the trails. We offer a non-binary registration option and awards category, and we are Trail Sisters approved. Ideas for doing better? Let us know!
