Cool start — fast day potential, moderate wind

A cool 47°F at the start line is ideal for fast times — expect to warm up quickly once you're moving. Moderate winds around 14mph may affect pacing on open sections of the course. Moderate humidity at 70% is worth noting for effort level, especially in later miles.
