Cougar Mountain Trail Run Series (October)
At a glance
Event Overview
Welcome to the 2025 edition of the Cougar Mountain Trail Run Series, put on by Seattle Running Club and Northwest Trail Runs. Our events support King County Parks, with a portion of every entry going to KC Parks.
Course Description & Map
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.
