Snohomish River Run Half Marathon
Race Day Weather
Cool start — fast day potential, chance of rain
A cool 46°F at the start line is ideal for fast times — expect to warm up quickly once you're moving. Temperatures rising to 56°F through the course will gradually increase perceived effort in the second half. There's a chance of rain, so have a backup gear plan ready. High humidity (81%) will make it harder to cool down through sweat — increase fluid intake accordingly.
