66° high
Breezy
Dry

Comfortable temps, warming through the race, moderate wind

Mild 54°F temps at gun time mean comfortable early miles without overheating risk. Temperatures rising to 66°F through the course will gradually increase perceived effort in the second half. Moderate winds around 14 mph may affect pacing on open sections of the course. Moderate humidity at 78% is worth noting for effort level, especially in later miles.
