A wild, remote Hardrock qualifier through the heart of Washington's Dark Divide
Other trail races within 77 miles
The Dark Divide 100 Mile Endurance Run is one of the most technically demanding 100-mile races in the Pacific Northwest. Winding through the 70,000-acre Dark Divide Roadless Area in Gifford Pinchot National Forest, this Hardrock 100 qualifier winds through serrated sub-alpine ridgelines, old-growth temperate rainforest, and remote river valleys with up to 16 miles between aid stations. With over 26,500 feet of gain and more than 75% singletrack—much of it raw and rugged—it demands wilderness navigation skills as much as fitness. A mandatory race briefing covers minimal course markings and extended self-sufficiency requirements. Cash prizes are offered for sub-24 hour women's and sub-20 hour men's finishes, and for first runners to complete five consecutive editions.
