The Chicago Marathon 2025 route has been officially revealed, and the city is getting ready to welcome over 53,000 runners for one of the most anticipated races of the year. Scheduled for Sunday, October 12, 2025, the event will transform Chicago into a vibrant celebration of running, community, and culture.
This year’s course sticks to the marathon’s signature flat and fast loop, but with a few smart updates to improve the experience for both runners and spectators. Whether you’re racing, cheering, or following from home, here’s a complete, easy-to-follow guide to the route, neighborhoods, changes, and race-day logistics.
🏁 Start and Finish: Grant Park
The Chicago Marathon starts and ends in Grant Park, the iconic green space at the heart of the city. This location has hosted the event for decades, offering a picture-perfect backdrop of skyscrapers and Lake Michigan.
- Start Line: Located on Columbus Drive, just north of Monroe Street, runners will begin in carefully organized waves starting early in the morning. Each wave ensures a smooth flow through the city’s streets.
- Early Miles: After crossing the start line, runners head north through the Loop. Towering buildings, bridges, and cheering spectators create an electric atmosphere that sets the tone for the race.
- Finish Line: After completing 26.2 miles, runners return to Grant Park to cross the finish line. This area includes medical tents, recovery zones, family meet-up points, and a festival-like celebration for finishers and fans.
This central start and finish location makes the marathon easy to access, whether you’re arriving by public transportation or supporting friends and family along the course.
🌆 A Tour Through 29 Neighborhoods
One of the most special parts of the Chicago Marathon 2025 route is its journey through 29 distinct neighborhoods. Each community brings its own energy, traditions, and character, giving runners a truly unique tour of the city.
Northern Loop (Miles 1–8)
- The Loop: The race kicks off in the city’s bustling downtown. The early miles are filled with energy, skyscrapers, bridges, and packed sidewalks full of spectators.
- River North & Old Town: The course winds north through trendy, historic areas with enthusiastic crowds and a mix of urban scenery.
- Lincoln Park: This leafy neighborhood offers a peaceful and scenic stretch, perfect for settling into a steady rhythm.
West Side (Miles 9–13)
- This part of the race shifts west into more urban, industrial sections like the West Loop. Crowds thin slightly here, making it a great time for runners to focus on pacing and hydration.
Cultural Corridor (Miles 14–22)
- Pilsen (Mile 19): Known for its vibrant murals, mariachi music, and passionate supporters, this is one of the most inspiring sections of the race. It’s also where many runners need that extra mental boost.
- Chinatown (Mile 21): Bright red lanterns, drummers, and enthusiastic fans welcome runners as they enter Chinatown. This late-race section provides both visual beauty and emotional energy for tired legs.
South Side to Finish (Miles 23–26.2)
- The final stretch takes runners along Michigan Avenue, a long, straight, flat road lined with spectators. This is where determination takes over as runners push through the last miles toward Grant Park.
- Crossing the finish line against the backdrop of the Chicago skyline is a moment runners never forget.
📝 Key Route Changes for 2025
While the 2025 route remains mostly the same, race organizers have made some smart adjustments to improve the overall experience:
- New Wentworth Avenue Segment: This year, runners will travel down Wentworth Avenue to 33rd Street, then turn east toward Michigan Avenue. This replaces a previous stretch that had limited spectator access.
- Better Crowd Movement: The new segment allows spectators to move more easily between neighborhoods, reducing congestion and improving visibility for those cheering on multiple runners.
- Optimized Aid Stations: Some water and medical stations have been repositioned, especially in the middle miles, to give participants better access when fatigue begins to set in.
These changes maintain the fast, record-friendly layout of the Chicago Marathon while making the race more enjoyable for everyone involved.
💧 Aid Stations and On-Course Support
The Chicago Marathon is known for its world-class organization, and the 2025 race continues that tradition.
- There will be 20 aid stations, roughly every 1–2 miles.
- Each station includes water, electrolyte drinks, medical personnel, portable toilets, and clear signage.
- Hydrogel fueling stations will be placed around miles 12, 16, and 18 to help runners maintain energy during the second half of the race.
- Enhanced medical support zones are positioned between miles 14–15 and at the finish line.
The official time limit is 6 hours and 30 minutes, which equals a pace of about 15 minutes per mile. Runners who fall behind this pace may not have access to every aid station but are still allowed to finish.
🚧 Street Closures and Transportation
Race day brings significant traffic changes across Chicago. If you’re a spectator, planning ahead is crucial.
- Streets along the route will close at 6:00 a.m. and reopen gradually by 4:00 p.m. after the final runners pass.
- Parking restrictions begin at 1:00 a.m. on race morning. Vehicles parked on closed streets will be towed.
- Key downtown roads, including Lake Shore Drive, Monroe Street, and Jackson Boulevard, will experience full closures.
Getting Around
The best way to travel on race day is the Chicago Transit Authority (CTA). Many train stations are located close to mile markers, making it easy to see runners at different points on the course without getting stuck in traffic.
👀 Top Spectator Spots
Some neighborhoods are especially fun and easy to access if you’re cheering from the sidelines:
