Cool start — fast day potential, warming through the race, moderate wind

A cool 48°F at the start line is ideal for fast times — expect to warm up quickly once you're moving. Temperatures rising to 60°F through the course will gradually increase perceived effort in the second half. Moderate winds around 13mph may affect pacing on open sections of the course.
