Runners will face temperatures starting at 68°F and climbing to 90°F by the finish. With high humidity at 82% and a light breeze from the NE, it's crucial to start conservatively and adjust pacing as the heat intensifies in later laps. Frequent hydration will be essential to combat the humidity. Light gear is recommended for optimal comfort throughout the race.
