Washington Half Marathon Calendar event dates in grey are delinquent dates not updated by the race organizer yet. We strive to have dates 1 year out for Washington Half Marathons, but have no control of when they set, announce or update their dates.
Washington Half Marathons
The Washington Half Marathon Calendar is a complete simplistic listing of Washington half marathons. Currently the Washington half marathon schedule has 2024 Washington half marathons and 2025 Washington half marathons as they roll in. Washington half marathons 2024 & Washington half marathons 2025 also identify trail half marathons and walker friendly half marathons by a (T) symbol and a (W) symbol. The (T) means it is a TRUE trail half marathon 21k (off road, switchbacks, etc) and a (W) means it is truly "official walker friendly" requiring the half marathon to allow a minimum of 18:32 mile pace, full supported, minimum of 4 hours to participants to finish the 13.1 mile distance.
The Washington half marathon calendar features a complete listing of Seattle half marathons, Tacoma half marathons, Spokane half marathons, Vancouver half marathons, Everett half marathons, Yakima half marathons, Bellingham half marathons, and many more 1/2 marathons in WA.
A half marathon is 13.1 miles (or in kilometers is a 21k). We understand sometimes there will be a slight margin of error up or down when runners run or walk any race distance, however our calendar only is a listing for true half marathons that do all they can to measure their course as an official half marathon 13.1 mile / 21k distance. Races that are not 13.1 miles, we encourage not to call their race a 1/2 marathon to lessen confusion for runners & walkers looking to participate in a true 1/2 marathon distance. Some runners don't care, but you'd be surprised how many that do.
