Cougar Mountain Trail Run Series #2
Cougar Mountain Trail Run Series #2 takes place at King County’s Cougar Mountain Regional Wildland Park in Newcastle, Washington, a park about 15 minutes from Seattle. The course network includes rolling, runnable hills and a variety of trail surfaces that range from narrow, technical single-track to wider, groomed paths. Runners pass through lush forest and fern-lined single-track, traverse hills and run along marsh areas.
Distances offered:
- 5 km
- 8.2 miles
- 14.5 miles
The event lists the Sky Country Trailhead off 166th Way SE as the registration and start location. The series has raised over $254,000 for King County Parks and has contributed many hundreds of hours of trail work. Seattle Running Club and Northwest Trail Runs are listed as partners for the series.
Past results and photos are available for recent years, including 2024, 2025, and 2026. Registration status is noted as "Registration coming soon."
Series competition rules require runners to compete in at least three of the four races in either the Short Series or the Long Series to be eligible for series standings. Scores from Short and Long races may not be combined; three or more results from one series are needed to rank in series standings. Visit the organization's website for the most recent information.
