Chicagoland Spring Marathon

Runners will face a temperature rise from 52°F at the start to 61°F by the finish, with humidity at 65%. Wind will be a factor, providing a tailwind from miles 4 to 7 and again from 12 to 16, while headwinds will challenge runners between miles 9-11 and 13-15. Adjusting pace on those exposed stretches will be crucial, especially during the headwind sections.
