Comfortable temps, chance of rain

Mild 51°F temps at gun time mean comfortable early miles without overheating risk. Temperatures rising to 60°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.
