Warm start, adjust pace wisely

Runners will face a warm start at 70°F, rising to 75°F by the finish, with high humidity at 95% making conditions feel more intense. A steady headwind will challenge runners from miles 2-4 and 13-14, while a brief tailwind from miles 9-10 may provide relief. It's crucial to pace conservatively early on and consider hydration strategies to combat the humidity.
