About the race

The Seattle Ghost Marathon is an annual event organized by NWUltras, a 501(c)(3) nonprofit. Race proceeds fund K-12 digital access programs and tools for students in underserved communities.

All races run along Lake Washington Boulevard and include a clockwise loop around Seward Park. The course is USATF measured and certified (WA09059MW) and is a Boston Marathon qualifier. The route is flat with minimal elevation change and aid stations stocked and staffed approximately every 3 miles.

Distances:

  • Half Marathon (13.1 mi) one loop around Seward Park and Lake Washington Boulevard
  • Marathon (26.2 mi) two loops of the half marathon course
  • 50K (about 31 mi) Seward Park lap, 0.52 mi out and back, then two marathon loops

Support at the finish includes heaters, tents, hot food, a finisher hoodie and a medal. Live timing and results are provided on ChronoKeep. The field is limited to 400 entries. The course is run mainly on sidewalks and cannot accommodate dogs, strollers, or wheelchairs.

Parking and logistics note that runners may be dropped off at the Ferdinand Street Boat Launch park; free neighborhood parking is available with no permit required. Volunteer opportunities are offered to support race operations and aid stations. Visit the organization's website for the most recent information.
