Cool start, manageable winds

Runners will face temperatures starting at 48°F and gradually rising to 53°F. Wind will peak at 12 mph from the SE, providing a tailwind between miles 3-5 and 14-17, while crosswinds will challenge runners through most of the race. With humidity at 61%, pacing strategies should remain conservative, especially in the early miles, to accommodate the gentle rolling terrain.
