Cool start, steady winds ahead

Runners will face a cool start at 43°F, gradually warming to 55°F by race end. Winds will be a headwind in the early miles and again from miles 12-18, reaching up to 11 mph, so pacing adjustments will be necessary during those stretches. The humidity at 74% suggests a need for hydration, especially in the later miles, while runners should dress warmly for pre-race conditions.
