Cool start, steady finish

Runners will face a temperature increase from 45°F at the start to 61°F by the finish. With a light wind from the WNW, it will feel comfortable, although the headwinds from miles 6-16 may challenge pacing. Runners should consider adjusting their pace conservatively during the early miles and ensure proper hydration as temperatures rise throughout the race.
