Pacific Northwest Marathon
Race Day Weather
Comfortable temps, big temp swing, chance of rain
Mild 52°F temps at gun time mean comfortable early miles without overheating risk. Temps will climb significantly to 71°F by later miles, so expect fading conditions as the race progresses. Light winds shouldn't be a major factor for pacing. There's a chance of rain, so have a backup gear plan ready. Moderate humidity at 71% is worth noting for effort level, especially in later miles.
