On Sunday, October 11, Chicago will welcome participants and spectators from around the world for the 48th running of the Bank of America Chicago Marathon, with the course traveling through 29 vibrant neighborhoods across the city. As the Chicago Marathon makes its way through your neighborhood, we’re reaching out with information about street closures, parking restrictions and other neighborhood impacts to help you prepare and share important race-day information with your community.
NOTE: This year's Bank of America Chicago Marathon course has changed between miles 1 and 2 in the Loop due to construction at State St. and Lake St:
2025 Chicago Marathon course: West on Grand Ave., south on State St., west on Jackson Blvd.
2026 Chicago Marathon course: West on Grand Ave., south on Dearborn St., west on Jackson Blvd.
In coordination with the City of Chicago, Clark Street will operate as a two-way street between Lake Street and Adams Street on Sunday, October 11 from 6:00 a.m. to 12:00 p.m. This temporary change will help drivers exit this area of the Loop when the Bank of America Chicago Marathon street closures are in effect in this area. Drivers will be directed north on Clark Street and east on Lake Street to Garvey Court where they can access lower Wacker Drive. Normal traffic patterns on Clark Street will resume once marathon-related closures are lifted.
