We acknowledge that our running opportunities are built on the purposeful removal of Native peoples, who have been the stewards of Seattle-area lands for thousands of years. Thus, we accept our ethical responsibility for the ongoing stewardship of the land and purposeful support of Native neighbors, colleagues, businesses, and tribes. The Muckleshoot, Duwamish, Stillaguamish, Snoqualmie, and Coast Salish are the Natives of the lands we run on.
I understand and accept that photos/videos/illustrations may be taken of me and/or my personal property while attending/participating in Seattle Running Club (SRC) events/functions. I acknowledge and agree that such photographs or other illustrations may be used by SRC and its related entities for advertising and promotional purposes in any medium, without compensation to me. If you would prefer not to have a particular photo used, let us know and we’ll do our best to remove it right away.
Again, this year the series is continuing to reduce the amount of trash created during the event. 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 Seven Hills Running, Fleet Feet Sports Seattle, and Snoqualmie Running have a variety of hydration products.
Thanks to runners like you, the Cougar Mountain Trail Run Series has raised over $250,000+ for King County Parks and contributed 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!
The summer Short Series and Long Series races are held on 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.
As much as we love our four-legged friends, we are not allowed to have dogs at our event due to USATF Sanctioning and Insurance Requirements.
The top 3 Men, Women, and Nonbinary Runners in each event will receive a podium prize.
