Thanks to runners like you, the Cougar Mountain Trail Run Series has raised over $254,000 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 21st annual event bigger and better than ever!
Just fifteen 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 at least three races in a series is eligible for Series awards. There are NO REFUNDS!
Come for a casual fun Thursday night run with the SRC crew! We will begin on the east side of the Garfield Community Center near the parking lot.
The route is ~6.5 mile with ~400 feet of elevation gain.
Some of us will grab drinks and dinner at Metier brewing after the run!
