Cool morning, steady crosswind

Runners will face temperatures starting at 45°F and rising to 50°F by the finish. Wind will be a consistent crosswind at 10 mph, with gusts up to 20 mph, but not a significant factor. With humidity at 72%, pacing should be conservative early, especially as the temperature increases during the later laps. A light throwaway layer is advisable for the pre-race warm-up due to the cooler feels-like temperature.
