Warm and humid, headwind challenge

Runners will face a warm start at 80°F, rising to 86°F by finish. Humidity will be high at 79%, making pace adjustments essential, particularly in the early miles with a headwind from miles 2-6. Wind gusts up to 21 mph will create challenges, especially during the exposed stretches. Hydration will be crucial throughout, and runners should consider a conservative start to manage the heat.
