Warming up, tailwind advantage

Runners will face a temperature rise from 56°F at the start to 71°F by the finish, with humidity around 58%. A light SW wind at 8 mph will provide a tailwind from miles 2 to 10, aiding speed, but headwinds will challenge runners from miles 14 to 21. Adjustments in pacing may be necessary as the race progresses, particularly in the warmer conditions.
