Just 15 minutes from Seattle, King County's Cougar Mountain Regional Wildland Park is one of the most popular training grounds for area trail runners and the Seattle Running Club. 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.
The series starts in May with the 5-mile event and concludes in October with a 20-mile/50K. Series standings are based on each runner's best three out of four race results from the 5-mile, 8-mile, 10-mile, and 13-mile. There is a participant cap and the races tend to sell out, so register early!
