Calling all runner: Registration for the 2025 Bank of America Chicago Marathon opens Tuesday.

The registration process comes less than a month after more than 50,000 runners took to city streets for the 2024 Bank of America Chicago Marathon.

Last week, registration for the 2025 Chicago 13.1 and Shamrock Shuffle 8K run opened with special discounted pricing. For the 2025 Bank of America Chicago Marathon, the four-week application period opens Tuesday.

Some runners may register for The Distance Series, which connects the three races in a challenge that requires runners to finish all three races in one year. Accomplishing the feat guarantees runners a spot in the 2026 Bank of America Chicago Marathon, along with an exclusive medal.

Those interested in participating in the Distance Series are encouraged to register and apply early to ensure their spots in the races.

Registration details for each race, including the 2025 Chicago Marathon are below.
