Cool conditions, manage rolling terrain

Runners will face temperatures starting at 59°F and peaking at 62°F, with high humidity at 80%. A steady tailwind from miles 3 to 14 will aid speeds, but headwinds from miles 17 to 25 will require pacing adjustments. With a rolling course profile, maintaining an even effort during climbs and descents is crucial, especially early on. Hydration should be prioritized given the humidity.
