Cool start — fast day potential, warming through the race

A cool 43°F at the start line is ideal for fast times — expect to warm up quickly once you're moving. Temperatures rising to 54°F through the course will gradually increase perceived effort in the second half. Light winds shouldn't be a major factor for pacing.
