Mild 55°F temps at gun time mean comfortable early miles without overheating risk. Temperatures rising to 64°F through the course will gradually increase perceived effort in the second half. Light winds shouldn't be a major factor for pacing. High humidity (92%) will make it harder to cool down through sweat — increase fluid intake accordingly.
