Cool start, moderate wind challenge

Runners will face a cool start at 49°F, rising to a maximum of 59°F. Wind will be a factor with a headwind during significant segments, particularly from Miles 2 to 11 and again at Mile 21. With humidity at 67%, hydration will be crucial, especially in the later stage of the race. Runners should adjust their pacing accordingly during headwind stretches and take advantage of the tailwind from Miles 14 to 19 and 23 to 25.
