About the Event

Discover a hidden urban oasis at the Frost Eagle Trail Run in Soaring Eagle Regional Park on Saturday, January 17, 2026. This winter trail event invites you to explore 600 acres of serene Sammamish forest, where twisting singletrack creates a playful, rollercoaster-like course over gentle, root-kissed terrain—a perfect redefinition of a "hill." Choose your adventure with a 5-mile or Half Marathon distance, both offering a tranquil escape into a sanctuary shared with deer, bobcats, and vibrant birdlife just minutes from the city. As the sixth race in the beloved Winter Trail Series, it’s an ideal opportunity to earn exclusive series socks, compete for season-long standings, or simply enjoy a crisp, community-focused run. With staggered starts, a supportive atmosphere, and the quiet beauty of the Pacific Northwest in winter, the Frost Eagle is more than a race—it’s a rejuvenating nature break. Lace up for a day where every turn brings a new perspective and the chill in the air sharpens the joy of the trail.
