Cool start, light rain possible

Runners will face a steady temperature from 40°F at the start to 44°F by the finish. With light winds from the SSW at 6 mph, conditions should remain manageable, but humidity at 82% may feel heavier. The potential for light rain means a cautious approach to hydration and pacing is advisable, particularly in the pre-race window.
