Comfortable temps, chance of rain

Mild 50°F temps at gun time mean comfortable early miles without overheating risk. 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 75% is worth noting for effort level, especially in later miles.
