Warm start, adjust pace early

Runners will face temperatures starting at 65°F and rising to 70°F. With humidity at 79% and a light headwind from the NE, pacing adjustments will be crucial. Given the chance of light rain, hydration should be prioritized, and runners should consider starting conservatively to manage the heat.
