Runners will face a start temperature of 57°F, rising to 72°F by the finish. With average humidity at 64%, hydration will be essential, especially as temperatures rise. Crosswinds will dominate early miles, but a headwind will challenge runners from mile 8 to 10 and again between miles 17 to 18. A brief tailwind from miles 11 to 12 and 15 to 21 will offer relief, making pacing adjustments crucial.
