Course details
The marathon follows a mostly downhill route with a consistent grade of about 2.2% and a net elevation loss of just over 2,000 feet. The marathon course includes passage through the Snoqualmie Tunnel. The half marathon covers the second half of the full course, has an approximate 1,100-foot net drop, and does not pass through the Snoqualmie Tunnel. Trails used include the Palouse to Cascade Trail and the Snoqualmie Valley Trail. Surface is packed gravel.
Registration and status
Severe storm damage to sections of the Palouse to Cascade Trail led organizers to pause registration while they work with permitting agencies on an alternate route. Washington State Parks has not confirmed whether alternate courses will be allowed. Registration was tentatively planned to reopen on February 1, 2026. The course has a history of producing Boston Marathon qualifiers, with reported rates above 40% for past editions. Visit the organization's website for the most recent information.
