Discover The Best Half Marathons in Washington
Washington's half marathon calendar is anchored by a handful of standout races: the Orca Half Marathon and Tacoma Narrows Half Marathon (which crosses the iconic Tacoma Narrows Bridge, along with its sister race Galloping Gertie), Beat the Blerch — created by Oatmeal cartoonist Matthew Inman in 2014 and known for its cult following — and the Mount Rainier Half Marathon, with views of the mountain from Tacoma's waterfront. Below, find the full 2026 half marathon calendar across the state.
