The History of Chicago

A tour of the Windy City

The Chicago Marathon was born in 1977, during the first running boom. What started as a local race has grown into one of the world's fastest and most beloved marathons, known for its incredible crowd support and iconic urban course.

The course is a tour of Chicago, winding through 29 diverse neighborhoods. Runners experience the city's incredible diversity—from the skyscrapers of the Loop to the vibrant streets of Pilsen, from Chinatown to Boystown, each neighborhood bringing its own energy.

Chicago's flat course and typically cool October weather have made it a favorite for runners chasing personal bests. The course has produced multiple world records, including Kelvin Kiptum's stunning 2:00:35 in 2023—the first time a human ran under 2:01.

The race starts and finishes in Grant Park, with the Chicago skyline providing a dramatic backdrop. The final stretch down Columbus Drive, with the city's towers rising ahead, is one of the most inspiring finishes in marathon running.

Chicago is known for its crowd support. An estimated 1.7 million spectators line the course, creating a wall of sound that carries runners through the final miles. It's often called the friendliest major marathon.
