Cool start, warming up, light wind

Runners will face a temperature rise from 53°F at the start to 68°F by the finish. Humidity will hover around 66%, necessitating a conservative pace early on. Light tailwinds will assist in the first half, but headwinds will challenge runners from miles 15 to 27, requiring strategic pacing adjustments. Hydration should be prioritized as temperatures climb, especially in the later miles.
