Snohomish River Run Marathon
Race Day Weather
Cool start — fast day potential, warming through the race, chance of rain
A cool 41°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. Moderate humidity at 76% is worth noting for effort level, especially in later miles.
