Warming up, mixed wind challenges

Runners will face a temperature rise from 58°F at the start to 72°F by race end, paired with a light average humidity of 36%. A headwind will impact efforts from miles 1-4, 11-17, and 24-26, making pacing adjustments necessary on these stretches. With a tailwind from miles 5-10 and 18-23, runners should capitalize on faster paces during those segments.
