Warm start, rising temperatures

Runners will face temperatures starting at 71°F and climbing to 79°F by the finish. Humidity will be high at 85%, which may make conditions feel warmer. With light winds under 5 mph, runners should focus on pacing conservatively in the early laps and stay hydrated throughout to combat the heat and humidity. Adjusting pace later in the race will be crucial as temperatures rise.
