Warm afternoon, adjust pace wisely

Runners will face a temperature rise from 61°F at the start to 73°F by the finish, with average humidity at 71%. A light headwind will affect miles 2, 9-10, and 14, while a beneficial tailwind will provide relief from miles 4 to 8. Given the heat and humidity, runners should consider starting conservatively and increasing hydration frequency, particularly during the challenging mile 11 climb.
