Comfortable temps, moderate wind, chance of rain

Mild 53°F temps at gun time mean comfortable early miles without overheating risk. Temperatures rising to 63°F through the course will gradually increase perceived effort in the second half. Moderate winds around 15mph may affect pacing on open sections of the course. There's a chance of rain, so have a backup gear plan ready.
