The race

This is the last race of the Evergreen Trail Runs season, and we will go out with a bang! There are lots of distance options to choose from – something for everyone: 5-mile, half-marathon, full marathon or 50K, and a kid's race.

Grand Ridge Park is an incredible setting to finish off this year. Since 2000, the Washington Trails Association has been hard at work developing miles of connected trail. It has all come together to create a beautiful system of trails that are ideal for running, hiking, and biking.

You'll be in the heart of the deep forests of the Cascade foothills. These lush, green forests are kept alive and thriving by the copious amounts of rain the region receives. So make sure to enjoy the fields of ferns and mossy trees with their golden fall colors showing. The trails are graded nicely, but don't let that fool you, you'll pack some climbing into this run!

  • Ratings: Intermediate
  • 5-Mile, Half, Full, 50K

The course

Rocky, technical switchbacks lead into rolling forest loops, and the "half" loop is closer to 14 miles. The season finale, with a distance for everyone.

Distances

Kid's race

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 Grand Ridge is a crushed gravel trail, with little elevation gain and is 1.1 mile long.

Registration FAQ

14 questions
Can I get a refund?

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. Cancelled or postponed races are not eligible for refunds.

What is the Refund Guarantee?

Optional refund protection you can buy through UltraSignUp when you register. It is run entirely by UltraSignUp.com. 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.

Can I transfer to a different Evergreen race?

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.

Race transfer instructions

Can I defer to next year?

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.

Deferral instructions

Can I switch to a different distance?

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.

Distance change instructions

Can I give my bib to someone else?

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.

Bib transfer instructions

What if I become pregnant after registering?

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.

How old do you have to be?
  • 5K and 5 mile: 12 and older may run independently, at their parent or guardian's discretion. Ages 8 to 12 may run if accompanied the whole way by an adult guardian who is also registered for the race. Under 8 may not run.
  • 10K and 12 mile: 16 and older may run independently. Ages 12 to 16 may run if accompanied the whole way by a registered adult guardian. Under 12 may not run.
  • Half marathon and longer (20 mile, marathon, 50K, 50 mile, 100 mile): 18 and older only.

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.

Is there a youth or senior discount?

Yes: runners 22 and under or 65 and over get 15% off the registration fee. Use the discount form linked on this page.

How are winners decided?

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.

Is there a non-binary category?

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.

What happens if the race is cancelled or postponed?

Our goal is always to provide an enjoyable, safe race experience. However, sometimes unusual conditions (weather and other) may require that, for your health and safety, we cancel a race. We never want to cancel a race and will do so only if the safety risk is great. While we can’t list every possible factor, some possibilities are extreme heat, extreme cold, hazardous air quality, unanticipated road/trail closures, dangerous animals on the course, or other natural or human-caused acts.

Whenever possible, we will postpone a race instead of cancelling it. When a race is postponed and you cannot make it to the new race date, you can defer to the following year’s race for free. Or if you’d prefer, you can transfer your entry to another Evergreen Trail Runs event in that same year for a reduced fee of $5. Cancelled or postponed races are not eligible for refunds.

Once the decision has been made to cancel a race, we will do our best to contact every registered participant as far in advance as possible. However, the very nature of many of these conditions may affect our ability to do so.

Can I bring my dog?

Dogs are welcome at the start and finish area, but not on the course.

Can I register on race day?

If the race has not sold out, yes. Cash (exact change), check, or card payment options available.

The full race policies are the final word on all of this.

Race day

Where: Grand Ridge Park, Issaquah, WA

Parking

Participants can park on the south side of the I-90, along SE 79th St, or in the I-90 Church parking lot (first left after passing the turn for the start/finish area). This is our largest race, so please carpool and park efficiently!

No Discover Pass is required.

Driving directions

Race registration and the start/finish area will be at Issaquah-Preston Trail High Point Way Trailhead; Exit 20 from I-90 in Issaquah, Washington.

The course in detail

The course is two distinct loops: one loop for the 5-mile run and another half-marathon(ish) loop for the longer distances. Marathon runners will do two loops of the half-marathon course, and 50K runners will do two half-marathon loops and then one 5-mile loop. We probably should note that the half-marathon loop is closer to 14 miles than 13 miles (gotta make up for those other missed races!)

All distances start from the Issaquah-Preston Trail High Point Way Trailhead and follow the Issaquah-Preston Trail for .5 miles before starting the climb. Rocky, technical switchbacks bring you up to the 5-mile course junction. The 5-mile takes a left and heads out on the loop of the lollipop, while the Half Marathon, Full Marathon, and 50K runners continue up Grand Ridge. They’ll take a detour from the out-and-back on the way north to visit the Flowing Fir Trail before coming back to the main trail and on an out-and-back to the Duthie Aid Station. The Full Marathoners get two loops of this awesome course. The 50K runners get two loops of the Half AND the 5-Mile loop. They get to see it all!

Course notes

The trails will be open to other users during the event, including pedestrians and cyclists. See our FAQ page for more information about sharing the trails.

Please note that distances and elevations noted and on the maps are approximate and are derived from online mapping programs. Your recorded distance and elevation gain on race day may vary.
