Comfortable temps, warming through the race, strong wind

Mild 51°F temps at gun time mean comfortable early miles without overheating risk. Temperatures rising to 62°F through the course will gradually increase perceived effort in the second half. Strong 25 mph gusts could slow exposed stretches — tuck behind other runners when you can. Moderate humidity at 69% is worth noting for effort level, especially in later miles.
