Cool start — fast day potential, big temp swing, moderate wind

A cool 43°F at the start line is ideal for fast times — expect to warm up quickly once you're moving. Temps will climb significantly to 60°F by later miles, so expect fading conditions as the race progresses. Moderate winds around 16mph may affect pacing on open sections of the course.
