Seattle Ghost Marathon, Half & 50K

The Seattle Ghost Marathon started in 1985 when the Seattle Marathon changed courses and moved from Saturday to Sunday of Thanksgiving weekend.

The course is a very flat and fast certified Boston Marathon qualifier. The marathon is comprised of two 13.1-mile loops run on streets and sidewalks along scenic Lake Washington in Seattle, WA.

The race start/finish is at the Ferdinand St Boat Launch in Seattle. It runs south with a clockwise loop of scenic Seward Park and back north to the start/finish area.  It continues north along Lake Washington through Leschi. The north turnaround is just past the Madrona Drive intersection, then you run south back to the start/finish. There are aid stations every 3.1 miles on each loop.

The race is managed and supported by two non-profit groups.  NW Ultras has been the driving force behind the event since 2004 and Green Lake Crew has supported the event since 2013.  It is limited to 400 total participants regardless of which event they run.
