Cool start, warming trend

Runners will face a temperature increase from 52°F at the start to 67°F by the finish. With a light tailwind from miles 2 to 7 and again from 13 to 14, conditions will support faster pacing in those segments. However, as the temperature rises, runners should adjust their pace conservatively, especially in the warmer late miles. Humidity remains manageable at 44%, allowing for effective hydration strategy throughout the race.
