Running Races in Seattle, Washington

Seattle's running calendar is anchored by the UW Medicine Seattle Marathon — the city's original hometown marathon and the oldest in the Pacific Northwest, starting near the Space Needle and finishing on the AstroTurf at Memorial Stadium each November. Beyond that, the calendar runs deep: the Orca Half Marathon, Lake Washington Half Marathon, and dozens of themed 5K/10K/half series races fill out nearly every weekend from summer through spring. Here are the upcoming races in Seattle, updated weekly.
