Cool conditions, adjust for wind

Runners will face a temperature trend starting at 52°F and finishing at 54°F, with a light rain expected. Winds will be a factor, with a headwind in Mile 1 and Mile 4, switching to a tailwind from Miles 8 to 12. Given the high humidity at 83%, pacing adjustments are recommended, especially during headwind segments, and runners should remain vigilant about hydration.
