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

A cool 42°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 22mph gusts could slow exposed stretches — tuck behind other runners when you can. Moderate humidity at 71% is worth noting for effort level, especially in later miles.
