Cool start, steady tailwinds

Runners will face a temperature rise from 41°F at the start to a peak of 53°F. With light winds from the SE at 8 mph, there will be tailwinds in the first two miles and again from miles 10 to 14, providing beneficial assistance. However, headwinds will be present from miles 3-6 and 8-9, so runners should conserve energy and adjust pacing accordingly during those stretches. Humidity is moderate; hydration should still be a priority.
