Comfortable temps, big temp swing

Mild 50°F temps at gun time mean comfortable early miles without overheating risk. Temps will climb significantly to 69°F by later miles, so expect fading conditions as the race progresses. Light winds shouldn't be a major factor for pacing. High humidity (87%) will make it harder to cool down through sweat — increase fluid intake accordingly.
