Cool start, steady headwinds

Runners will face a cool start at 47°F, rising to 54°F by the finish. Winds will be a significant factor, with a consistent headwind from miles 3-8 and 20-21, making pacing adjustments crucial during those segments. Humidity levels at 65% suggest a need for hydration, especially as temperatures increase. A light layer may be beneficial during the pre-race warm-up due to the potential for a chilly feel.
