Seattle Ghost Marathon, Half & 50K

Seattle Ghost Marathon, Half & 50K takes place in Seattle, Washington, on November 28, 2026, with three distances released in reverse order of length. The 50K (31 miles) leaves at 6:00 a.m., the marathon (26.2 miles) at 7:00 a.m. and the half marathon (13.1 miles) at 8:00 a.m., so the fields spread out from the start and the longest race gets the most daylight.

An ultra on the same card as a half tells you who this event is for: runners comfortable with time on their feet. The 50K asks for a sixteen-week build with back-to-back long runs on the weekend, and the marathon for something similar minus the ultra-specific volume. The half is the entry point, and a 6:00 a.m. alarm is worth rehearsing in training if you enter the 50K, since a pre-dawn start changes your whole fuelling plan.
