The event takes place in Seattle, WA on November 29, 2026. It features a full marathon and a half marathon held on a course described as having rolling hills and scenic views of Seattle bridges, waterways and architecture. The event identifies itself as Seattle's original hometown marathon and the oldest marathon in the Pacific Northwest, running since 1970.
An accompanying Health and Fitness Expo is scheduled in the days before the race on November 27 and 28.

Special registration groups are available, including comped entries for athletes who meet qualifying times within the last two years, discounted entries for sub elite athletes and active military, and comped entries for pacers and ambassadors. Support runners who assist a registered participant are also accommodated and receive a matching bib and finisher medal but are not competitively timed.
All in person participants receive a long sleeve participant shirt, a race bib, and a finisher medal.
