Mill Race Half Marathon
Race Day Weather
Comfortable temps, big temp swing
Starting at 61°F, heat will be a factor from the gun — go out conservative and stay on top of hydration. Temps will climb significantly to 78°F by later miles, so expect fading conditions as the race progresses. Light winds shouldn't be a major factor for pacing. Moderate humidity at 67% is worth noting for effort level, especially in later miles.
