Belleville Main Street Marathon
Race Day Weather
Comfortable temps, big temp swing
Mild 58°F temps at gun time mean comfortable early miles without overheating risk. Temps will climb significantly to 77°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 66% is worth noting for effort level, especially in later miles.
