Washington

Seattle hosts the Seattle Marathon and Half Marathon each November and the Orca Half Marathon, and the Bellingham Bay Marathon, run each September along the bay, has become a regular target for runners chasing a Boston qualifying time. Head into the Cascades and the calendar turns technical, with most of the state's biggest ultras falling between July and October. Snoqualmie alone hosts Ultra Fest's 50K-to-100-mile lineup and the Teanaway Country 100 Mile/50 Mile/50K, and Deception Pass adds a 50K and 25K on the coast. East of the mountains, Leavenworth's Bavarian-village marathon and the Spokane Marathon anchor the drier side of the state.
