Comfortable temps, big temp swing

Mild 58°F temps at gun time mean comfortable early miles without overheating risk. Temps will climb significantly to 76°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.
