Comfortable temps, warming through the race, chance of rain

Mild 54°F temps at gun time mean comfortable early miles without overheating risk. Temperatures rising to 67°F through the course will gradually increase perceived effort in the second half. Light winds shouldn't be a major factor for pacing. There's a chance of rain, so have a backup gear plan ready. Moderate humidity at 78% is worth noting for effort level, especially in later miles.
