Racing in Seattle

The Seattle race calendar is busiest in October, September, and November. It covers a range of endurance sports — you'll find races in Running, Trail Running, Obstacle Course, and Ultramarathon — so there's usually a race near you. Distances span a wide range across those sports; you'll see 5K, 10K, Half Marathon, 1 Mile, and 15K, along with other popular distances.

Weather on race day varies by time of year, so it lives where it’s accurate — each race page shows that race’s typical high, low, and rain chance from NOAA climate normals for its venue and date.
