Cool conditions, adjust for wind

Runners will face temperatures starting at 59°F and rising to 62°F. Wind will be a steady headwind at 16 mph, with gusts up to 23 mph, making pacing adjustments necessary. With 75% humidity, maintaining hydration is crucial, and runners should consider starting conservatively to account for the wind's impact.
