Hyak Halloween 25k

The Hyak Halloween 25K is a trail running event held at Snoqualmie Pass, Washington, on the ancestral lands of the Snoqualmie Tribe. The 25-kilometer course features a unique and spooky highlight: runners pass twice through the 2.25-mile-long, 110-year-old Snoqualmie Tunnel, known for its eerie atmosphere. The route combines smooth gravel sections on the Palouse to Cascades Trail with moderately steep, rooty single-track trails leading to Annette Lake, showcasing beautiful fall colors.

With 1,800 feet of elevation gain and two aid stations, the event welcomes both new and experienced trail runners. Costumes are encouraged, emphasizing cultural respect and non-gory themes. The event focuses on mindful recreation rather than competition, with a generous 7.5-hour time limit to complete the course. Visit the organization's website for the most recent information.
