Runners must complete the 26.2-mile course within 6 hours and 30 minutes. That works out to a pace of 15 minutes per mile. A pace vehicle follows the last starter and signals course reopening to traffic when the time limit is reached.
The Course: Flat, Fast and Full of Character
The Chicago course is famous for one reason above all others: it is remarkably flat. Net elevation change is close to zero. There is only one notable incline in the entire 26.2 miles. That is the small bridge over Roosevelt Road near mile 26, affectionately nicknamed “Mount Roosevelt.” It arrives in the final half-mile and, on tired legs, it feels much steeper than it actually is.
The course starts in Grant Park, heads north through the downtown Loop, then swings through River North, Old Town, Lincoln Park, and Lakeview before turning south. From there, runners pass through Greektown, Little Italy, Pilsen, Chinatown, Bronzeville, and the South Loop before the final stretch back to the Grant Park finish.
In total, the route passes through 29 of Chicago’s diverse and vibrant neighborhoods. More than 1.7 million spectators line the streets on race day, making it one of the most energetic and well-supported marathons anywhere in the world.
The course has produced seven world records over the years. Most recently, Kelvin Kiptum set the men’s world marathon record of 2:00:35 here in October 2023, and Ruth Chepngetich broke the women’s world record with a stunning 2:09:56 at the same event. The flat profile and typically cool October temperatures continue to attract runners chasing fast times.
However, runners should note that GPS watches perform unreliably in the early miles, where downtown skyscrapers block and reflect signals. A pace band or a manual split strategy is a smarter option for anyone targeting a specific finish time.
How to Register for the 2026 Race
The general application window for 2026 has now closed. However, there are still ways to secure your place on the start line.
The Charity Program remains open on a first-come, first-served basis until Tuesday, September 15, 2026, or until individual charities reach their capacity. Each charity sets its own fundraising requirements and participant benefits. Dozens of official charities are part of the program, including the American Cancer Society.
The Tour Operator Program also offers guaranteed entries. International runners who book through an official tour operator can secure a place along with a travel package that typically includes flights, hotels, and event logistics support. The tour operator application window remains open through Sunday, August 16, 2026.
Entry fees for the 2026 race are $250 for US residents and $260 for runners based outside the United States.
Additionally, runners who qualify through time standards can secure guaranteed entry. Qualifying times are based on age and gender, with the standard for men aged 16 to 29 set at sub-3:10 and for women at sub-3:35. Times are calculated based on each athlete’s age on October 11, 2026.
Legacy finishers who have completed the race five or more times within the last ten years also receive guaranteed entry.
Packet Pickup: The Abbott Health and Fitness Expo
Every registered runner must collect their race bib and timing chip in person before race day. There are no exceptions. Athletes who miss the expo cannot participate.
Packet pickup takes place at the Abbott Health and Fitness Expo at McCormick Place, located at 2301 South Martin Luther King Drive in Chicago. The expo runs Thursday, October 9, through Saturday, October 11. Hours are 10 a.m. to 6 p.m. on Thursday, 9 a.m. to 6 p.m. on Friday, and 9 a.m. to 6 p.m. on Saturday.
The expo is also a major event in its own right. Hundreds of running brands, nutrition companies, and gear suppliers exhibit there. It is a great opportunity to pick up last-minute supplies, test products, and soak up the pre-race atmosphere. Plan to spend at least a couple of hours browsing after you collect your bib.
Runners must bring a valid photo ID to collect their packet. Only the registered participant can pick up their own bib. No exceptions apply.
Spectator Guide: Where to Watch and How to Get There
Chicago is one of the best marathon cities in the world for spectators. The route winds through 29 neighborhoods, and the city’s train network makes it easy to move between viewing spots throughout the morning.
Spectators cannot access the start and finish areas within Grant Park until 9:30 a.m. However, there are excellent viewing locations along the full length of the route.
Some of the best spots to watch include Grand Avenue near mile 1, Clark Street through Old Town around mile 7, the electrifying Boystown neighborhood around miles 7 to 9, Pilsen around mile 18 where mariachi bands play in the streets, and Chinatown around mile 21 where enthusiastic crowds and colorful lion dancers greet passing runners.
The CTA rail system is the fastest and most reliable way to move around the course on race day. Board the Red Line to Grand Avenue for miles 1 and 3, use the Orange Line to reach Halsted at mile 20.5, or take the Green Line to 35th-Bronzeville-IIT for mile 23. For the finish, take any Red, Green, or Orange Line train to Roosevelt Station and walk east toward Grant Park.
After the race, the 27th Mile Post-Race Party opens in Butler Field inside Grant Park at 9:30 a.m. Music, food, and beverages are available. Finishers aged 21 and over can redeem the tear-off portion of their bib for one complimentary beer. The party runs until 4 p.m.
Runner reunions take place at alphabetically marked towers in Butler Field, labeled A through Z by last name. This helps families and friends locate their runners in what can be a very large post-race crowd. Plan a specific meeting point and letter in advance.
