Endurance Grid lists 305 running races in Washington, from September 2026 to August 2027 across 82 cities.
The running race calendar in Washington is busiest in October, November, and September, with races most often in Seattle, Spokane, Everett, and Puyallup.
Organized running races are one of the most accessible entry points into endurance sports. There’s a distance for every fitness level and a community at every start line. Distances run from 1-mile fun runs and 5Ks up through the 10K, half marathon, and marathon.
Most races are timed and chip-scored, with a mass or wave start and aid stations along the course. Big-city races keep the noise going the whole way; smaller races give you long stretches where it’s just you and the miles.
