Cool start, headwinds early

Runners will face a temperature rise from 46°F at the start to 61°F by the finish, with humidity averaging 69%. A headwind from 2 to 5 miles will challenge pacing, so athletes should conserve energy early. As temperatures warm, maintaining hydration will be crucial. Tailwinds from miles 8 to 12 may provide relief, allowing for a stronger push toward the end.
