***Summer Series Cancelled***
The 2020 Cougar Mountain Trail Run Series is cancelled due to impacts of the COVID-19 pandemic. Please note the October 25th Cougar race is outside the series and will proceed as planned at this time. We are refunding all runners for series (June-September) registrations.
Thanks to runners like you, the Cougar Mountain Trail Run 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 14th annual event bigger and better than ever!
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!5,000

A Greener Event: No Cups!
Again, this year the series is continuing to reduce the amount of trash created during the event. In 2019, we ask that runners bring a refillable water container with them on the trail to use at aid stations along the way. Our friends at Shoes-n-Feet, Seven Hills Running, and Fleet Feet Sports Seattle have a variety of hydration products.
No Dogs Please.
Very important announcement: 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.
