Cool conditions, adjust for wind

Runners will face temperatures starting at 55°F and rising slightly to 57°F by race end. A steady ENE wind reaching 11 mph will create headwinds in multiple segments, particularly from miles 2-8 and 11-12, necessitating pace adjustments. With high humidity at 79%, it’s advisable to maintain hydration strategies throughout the race, especially on the rolling terrain where wind may impact performance.
