Registration Opens for Chicago’s 2026 Iconic Race Series as 2025 Marathon Nears

 As thousands of runners across the globe make their final preparations for the 2025 Bank of America Chicago Marathon, excitement is already building for next year’s races. Organizers have announced that registration is now open for those who wish to participate in Chicago’s series of iconic running events in 2026.

The Chicago Marathon, one of the world’s most famous races, draws elite athletes and amateurs alike to the city each October. The upcoming 2025 event will see runners from more than 100 countries competing through the city’s scenic neighborhoods, cheered on by enthusiastic crowds.

For those who can’t wait to experience the thrill of running through Chicago’s streets, the registration for next year’s race series — including the marathon, half marathon, and 5K — is now available online. Early registration ensures a better chance of securing a spot, as the events often sell out quickly.
