Cool start — fast day potential, strong wind

A cool 46°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. Strong 20mph gusts could slow exposed stretches — tuck behind other runners when you can.
