Cougar Mountain Trail Run Series #4 5K | 14.5 Mi | 26.2 Mi
August 12, 2023 @ 6:30 am - 3:30 pm PDT
An event every year that begins at 6:30 am on day second of August, repeating until August 9, 2025
Just 15 minutes from Seattle, King County’s Cougar Mountain Regional Wildland Park is one of the most popular training grounds for area trail runners and the Seattle Running Club. The course builds on itself throughout the series and brings runners through a lush forest of fern-lined single-track trails, over hills and along marshes and wetland habitats. This is a great series to supplement the training regime for a fall marathon or ultra. Cougar Mountain features rolling hills, a few moderate climbs and a few steep but short inclines.
The summer Short Series and Long Series races are held the 2nd Saturday of May, June, July, and August. The Fall races are held on the last Sunday in October. Series standings are updated after each month’s races and everyone competing in each successive distance is eligible for Series awards. There is a participant cap and the races tend to sell out, so register early!
Thanks to runners like you, this series has raised over $170,000 for King County Parks and contributed many hundreds of hours of trail work. Join Seattle Running Club and Northwest Trail Runs in carrying this legacy forward and making this annual series bigger and better than ever!

No Dogs Please
Dogs are not allowed on the course due to USATF Sanctioning and Insurance Requirements. Despite the parks policy on dogs on leash being acceptable, USATF has determined dogs on course cause a potentially unsafe environment for participants and spectators. We love our dogs and remember Scott’s dog Jack attending Cougar races for years and years. But we want to continue hosting races for years to come and need to abide by the USATF rules.
