Comfortable temps, chance of rain

Mild 57°F temps at gun time mean comfortable early miles without overheating risk. Temperatures rising to 66°F through the course will gradually increase perceived effort in the second half. There's a chance of rain, so have a backup gear plan ready. Moderate humidity at 80% is worth noting for effort level, especially in later miles.
