Cool conditions, moderate wind impact

Runners will face cool temperatures starting at 39°F and rising to 41°F by the finish. With a light SSW wind and gusts up to 21 mph, the tailwind from miles 2-7 will aid pacing, but headwinds from miles 9-12 may require additional effort. Given the cool start, pacing adjustments should be made to maintain rhythm without overexertion on the rolling terrain.
