The Chicago Marathon is one of the Abbott World Marathon Majors and has earned a reputation as one of the fastest marathons in the world. While it may not boast quite as many internationally recognised landmarks as London or New York, it more than makes up for it with exceptional organisation, enthusiastic crowds and a remarkably flat course.
If you're chasing a personal best, working towards your Abbott World Marathon Majors Eight Star Medal or simply looking for an unforgettable marathon experience, Chicago deserves a place on your running bucket list. From the moment you arrive in Grant Park until you cross the finish line 26.2 miles later, every aspect of race weekend has been designed with runners in mind.
Why Run The Chicago Marathon?
Every October around 50,000 runners from more than 100 countries travel to Chicago to take part in one of the world's most prestigious marathons. The event combines the excitement of a major city with the warmth of Midwestern hospitality, creating an atmosphere that is welcoming whether you are an elite athlete or running your very first marathon.
The Chicago Marathon is especially popular with runners looking to achieve a personal best. The roads are wide, the course is almost completely flat and the cool autumn temperatures often provide near perfect marathon conditions. Add in world class organisation and enthusiastic spectators, and it is easy to understand why so many runners return year after year.
For runners completing the Abbott World Marathon Majors series, Chicago is often regarded as one of the quickest races in which to achieve a fast time. Whether it is your first Major or one of the final events on your journey towards the Abbott World Marathon Majors Eight Star Medal, the experience is one you are unlikely to forget.
About Chicago
Located on the shores of Lake Michigan, Chicago is America's third largest city and is famous for its impressive skyline, striking architecture and vibrant cultural scene. It is a city that is easy to explore, with many of its best attractions, restaurants and hotels located within walking distance of Grant Park.
Visitors can spend time admiring the city's famous skyscrapers, exploring the renowned Art Institute of Chicago or taking a boat tour along the Chicago River to appreciate the city's architectural heritage. Millennium Park is home to Cloud Gate, better known as The Bean, while Buckingham Fountain has become one of Chicago's most recognisable landmarks.
Chicago is equally well known for its theatres, live music, sporting history and outstanding food scene. Whether you want to sample the famous deep dish pizza, enjoy a steakhouse or relax in one of the many waterfront bars after the marathon, there is something for every visitor.
Accommodation ranges from budget hotels to luxury properties, although race weekend is always busy. Staying close to Grant Park allows runners to walk to both the start and finish, making race morning significantly less stressful.
The History Of The Chicago Marathon
The first Chicago Marathon took place in 1977 with just over 2,000 finishers. Since then it has grown into one of the largest and most respected marathons in the world, welcoming well over one million finishers throughout its history.
The race has become famous for producing fast times. Numerous world records have been broken on Chicago's streets, with elite runners regularly targeting the event because of its flat profile and favourable weather conditions.
One of the most memorable performances came in 2023 when Kenya's Kelvin Kiptum ran an astonishing 2:00:35 to set a new men's marathon world record. That same year course records were also broken in the women's race and both wheelchair races, reinforcing Chicago's reputation as one of the fastest marathon courses anywhere in the world.
Chicago has continued to attract many of the world's greatest marathon runners and remains one of the highlights of the Abbott World Marathon Majors calendar.
Who Organises The Chicago Marathon?
The event is organised by Bank of America, whose long term investment has helped establish the race as one of the world's leading marathons. Every aspect of race weekend is professionally managed, from the registration process and Expo through to baggage handling and the finish area.
Many experienced marathon runners consider Chicago to be one of the best organised races they have ever completed, with excellent communication before the event and outstanding support throughout race weekend.
When Is The Chicago Marathon?
The Chicago Marathon takes place every October. The 2026 edition is scheduled for Sunday 11 October 2026.
The Abbott Health & Fitness Expo
Every participant must collect their race number from the Abbott Health & Fitness Expo, which takes place over three days at McCormick Place, one of the largest convention centres in North America.
The Expo features more than 100 exhibitors showcasing the latest running shoes, clothing, nutrition products and recovery equipment. It is also the best place to purchase official marathon merchandise, much of which sells out before race day. Many runners allow several hours to explore the exhibition, meet exhibitors and soak up the excitement before the marathon.
How Many Runners Take Part?
Approximately 50,000 runners take part in the Chicago Marathon every year, making it one of the largest marathons in the world. Hundreds of thousands of spectators line the streets throughout race day, creating an incredible atmosphere from start to finish.
The Course
The marathon starts and finishes in Grant Park, a huge green space on the edge of Lake Michigan that provides one of the best start and finish areas of any major marathon. Unlike some races where runners feel crowded before the start, Chicago offers plenty of space to warm up, prepare and meet friends and family afterwards.
The wide roads also help the field spread out quickly, reducing congestion during the opening miles and allowing runners to settle into their target pace much earlier than at many other major marathons.
Grant Park
Grant Park is often referred to as "Chicago's Front Yard" and provides a spectacular setting for both the start and finish. Covering more than 300 acres, it is home to Buckingham Fountain, beautiful gardens, sporting facilities and several of the city's biggest festivals throughout the year.
Its central location makes it easy for supporters to reach on race morning, while the spacious layout means runners have plenty of room after crossing the finish line. It is one of the reasons why Chicago is often praised for its excellent race day logistics.
The Magnificent Mile
Within the opening miles runners reach Michigan Avenue, better known as the Magnificent Mile. This famous boulevard is lined with luxury shops, historic buildings and some of Chicago's most impressive skyscrapers, offering spectacular views as the race begins.
The crowds are already several people deep at this stage, creating an electric atmosphere that helps settle pre race nerves and carries runners through the opening section of the course.
Lincoln Park
Between miles four and seven the course passes through Lincoln Park, one of Chicago's most attractive neighbourhoods. The tree lined streets, elegant homes and nearby lakefront provide a welcome contrast to the towering buildings of downtown Chicago.
This area is also home to Lincoln Park Zoo, one of the oldest free zoos in the United States, while local residents create a fantastic atmosphere that continues throughout this section of the race.
The West Loop And Union Station
Around halfway runners pass close to Union Station and the West Loop district. Union Station is one of America's great railway terminals and remains one of Chicago's architectural highlights, with its magnificent Great Hall and impressive vaulted ceiling.
Reaching halfway provides an important psychological boost, particularly for first time marathon runners. The atmosphere remains strong as spectators continue to line the streets, encouraging runners through every neighbourhood.
Chicago's Diverse Neighbourhoods
One of the defining features of the Chicago Marathon is the opportunity to experience the city's remarkable diversity. The course passes through almost 30 different neighbourhoods, each bringing its own culture, music and atmosphere to race day.
Greektown welcomes runners with lively restaurants and enthusiastic supporters, while Little Italy adds another distinctive character to the route. Pilsen celebrates Chicago's Mexican heritage with colourful murals, music and community celebrations that create one of the most vibrant sections of the marathon.
Perhaps the biggest highlight comes in Chinatown with around five miles remaining. Traditional music, colourful decorations and enthusiastic crowds provide a huge lift just when many runners begin to feel the effects of the distance. The constantly changing scenery means the course never feels repetitive despite its flat profile.
The Final Miles
The closing miles lead runners back towards Grant Park and the shores of Lake Michigan. Although the finish is not quite as iconic as Central Park in New York or The Mall in London, the sense of achievement is every bit as memorable.
The finish area is spacious and extremely well organised, allowing runners to collect their medal, refreshments and baggage with minimal delays. Once recovered, many participants take the short walk to Millennium Park or Buckingham Fountain before celebrating with one of Chicago's famous deep dish pizzas.
Supporting A Runner
Chicago is an excellent marathon for spectators because the city's public transport network makes it relatively easy to move between different viewing locations. Friends and family can often see runners several times during the race before returning to Grant Park for the finish.
The finish area is also far less congested than many other major marathons, making it much easier to reunite after the race and begin celebrating your achievement together.
Charity Fundraising
The Chicago Marathon has one of the largest official charity programmes in North America. More than 190 official charity partners offer guaranteed entries each year, with hundreds of millions of dollars having been raised for good causes since the programme began.
For runners who miss out in the ballot, a charity place is often the most popular alternative. It provides guaranteed entry while giving participants the opportunity to support a cause that is important to them and make their marathon experience even more meaningful.
How To Enter The Chicago Marathon
Most runners enter through the annual ballot, which attracts huge demand from around the world. If you are unsuccessful there are still several alternative routes into the race, including qualifying through the published time standards or booking through an authorised international tour operator.
Another popular option is to secure a guaranteed place through one of the official charity partners. This allows runners to combine one of the world's greatest marathon experiences with the opportunity to raise vital funds for a worthwhile cause.
Our Verdict
The Chicago Marathon quietly delivers one of the finest marathon experiences anywhere in the world. It may not have quite the instantly recognisable landmarks of London or the unforgettable journey through New York's five boroughs, but it excels in almost every other area.
The organisation is outstanding, the course is exceptionally fast and the atmosphere created by Chicago's diverse neighbourhoods makes every mile enjoyable. Whether you are chasing a personal best, working towards your Abbott World Marathon Majors Eight Star Medal or simply looking for your next marathon adventure, the Chicago Marathon is a race that deserves a place near the very top of every runner's bucket list.
