Washington Half Marathon Races

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, and the Mount Rainier Half Marathon, with views of the mountain from Tacoma's waterfront. Below, find the full 2026-27 half marathon calendar across the state.
