About

A welcoming mountain trail race from Hyak at Snoqualmie Pass: through the completely dark 2.25-mile Snoqualmie Tunnel, up rooty, rocky singletrack to Annette Lake, and back the way you came. Around 1,800 ft of climbing, two staffed aid stations and 7.5 hours of course support — a headlamp is required for the tunnel. Formerly Rainshadow Running's Hyak Halloween 25K, now organized by Cielo Running, a family-owned and BIPOC-owned Pacific Northwest trail race company.
