Comfortable temps, moderate wind, rain likely

Mild 52°F temps at gun time mean comfortable early miles without overheating risk. Moderate winds around 14mph may affect pacing on open sections of the course. Rain is likely — waterproof your phone and bib, and consider a disposable poncho for the corral. Moderate humidity at 80% is worth noting for effort level, especially in later miles.
