Cool conditions, steady tailwind

Runners will face a cool start at 53°F with conditions remaining steady throughout the race. A light tailwind will aid performance from miles 1 to 4 and again from miles 6 to 27, while a crosswind at mile 5 may require slight adjustments. With humidity at 57%, maintaining hydration is key, especially as temperatures reach a maximum of 55°F by the finish.
