Cool start, warming finish

Runners will face temperatures rising from 57°F at the start to 66°F by the finish, with humidity at 80%. A light to moderate wind from the ENE will create crosswinds in the early miles, switching to a tailwind between miles 3 to 16, then turning into a headwind from miles 17 to 25. Runners should pace conservatively in the early stages to manage the heat, especially as they approach the warmer finish.
