Runners will face a temperature rise from 50°F at the start to a peak of 71°F by the finish. With light winds from the west and gusts up to 20 mph, the wind will not significantly affect pacing early on. However, runners should prepare for headwinds from miles 14 to 21, making those sections particularly challenging. Starting conservatively is advised, especially as temperatures climb, to maintain energy for the hilly terrain.
