Hot start, moderate wind

A warm 76°F start means heat management is critical — consider dialing back your goal pace by 10-20 sec/mi. Temperatures rising to 85°F through the course will gradually increase perceived effort in the second half. Moderate winds around 12 mph may affect pacing on open sections of the course. Moderate humidity at 71% is worth noting for effort level, especially in later miles.
