Runners will face cool temperatures starting at 44°F, rising slightly to 45°F by the finish. A light headwind will be present during the first mile and at multiple intervals, particularly from miles 7-10 and 14-18, which may affect pacing. With humidity at 94%, maintaining hydration is crucial, but the mild temperatures should allow for a steady effort throughout the gently rolling course.
