About the Seattle Ghost Marathon
The Seattle Ghost Marathon started in 1985, when the Seattle Marathon changed courses and left Thanksgiving Saturday open. NW Ultras, a nonprofit, has kept the date alive ever since, and the race now draws runners who want a quiet, flat, certified course while the city's bigger race runs the next day.
Course
Two 13.1-mile loops run along Lake Washington from the Ferdinand Street Boat Launch. Each loop circles Seward Park, then heads north through Leschi to a turnaround near Madrona before returning. The route uses streets and sidewalks, stays flat, and puts an aid station roughly every three miles.
Race-day weather
Late November in Seattle usually means temperatures in the 40s, gray skies, and a real chance of rain. Wind off the lake can add chill on the exposed shoreline miles, so layers that handle drizzle matter more than heat planning.
