Cool morning, gradual warm-up

Runners will face a start temperature of 50°F, gradually warming to 60°F. Humidity will be moderate at 68%, with a light breeze from the WSW, mostly non-factor. Key pacing adjustments should be made during miles 9-13 where headwinds will challenge runners, while a tailwind during miles 15-18 will provide a welcome boost. A light rain is possible, so a throwaway layer may be wise for the pre-race wait.
