Cool start — fast day potential, big temp swing

A cool 50°F at the start line is ideal for fast times — expect to warm up quickly once you're moving. Temps will climb significantly to 72°F by later miles, so expect fading conditions as the race progresses. Light winds shouldn't be a major factor for pacing.
