Frost Eagle Trail Run
Sammamish, United States • 17 Jan 2026
Frost Eagle Trail Run is held at Soaring Eagle Regional Park in Sammamish, WA, a 600-acre sanctuary of birds, deer, and wetlands with about 12 miles of trails. The event features 5-mile and half-marathon distances and marks the sixth stop in Northwest Trail Runs’ Winter Trail Series. Runners navigate rolling, mostly technical singletrack with a short section on the Pipeline Trail (gravel). The trails form a figure-8, so half-marathoners complete two laps and 5-milers one lap, with aid stations along the loop and an additional aid area near the start/finish for the half. Series swag and a points-based standings system reward consistent participation. Visit the organization's website for the most recent information.
