Comfortable temps, rain likely

Mild 55°F temps at gun time mean comfortable early miles without overheating risk. Light winds shouldn't be a major factor for pacing. Rain is likely — waterproof your phone and bib, and consider a disposable poncho for the corral. High humidity (91%) will make it harder to cool down through sweat — increase fluid intake accordingly.
