Cougar Mountain Trail Run Series #3

July 9, 2022

This is the third race in this classic trail running series, with a Short Series 10.8-mile race, and a Long Series 19.5-mile race, as well as a short and fast 5k. 9:00am start.

This event is co-sponsored by Seattle Running Club and Northwest Trail Runs, and it features clearly-marked courses, well-stocked aid stations, and friendly staff.

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 14th annual series bigger and better than ever!

Just 15 minutes from Seattle, King County’s Cougar Mountain Regional Wildland Park, is a trail running paradise thanks to its rolling and runnable hills and trail variety ranging from narrow and technical to wide and groomed. Run through lush forest, fern-lined single-track, over hills and along marshes, just minutes from the city.
