Cougar Mountain Trail Run
Bellevue, United States • 10 May 2025
The Cougar Mountain Trail Run Series, organized by the Seattle Running Club and Northwest Trail Runs, takes place in King County's Cougar Mountain Regional Wildland Park. The event features various distances, including 5.1 miles and 10.8 miles, with additional series options throughout the summer. Participants can enjoy well-marked trails, community engagement, and post-race refreshments, all while supporting King County Parks, as a portion of the entry fees is donated to park maintenance. The series promotes a greener event by encouraging runners to bring refillable water containers. This annual event has raised over $250,000 for local parks and fosters a vibrant trail-running community. Visit the organization's website for the most recent information.
