Chicago Running: World Major Speed and Urban Flats
Running in Chicago, the massive metropolis on Lake Michigan, is synonymous with speed and global competition. The Chicago Marathon is a World Marathon Major and is internationally recognized as one of the fastest, flattest marathon courses on the planet. Utilizing the city’s minimal elevation change and grid system, the route is meticulously designed to maximize pace, consistently yielding world-class times and acting as a premier destination for runners aiming for a significant personal best (PB).

The course offers an unparalleled sightseeing tour, taking runners through an astounding twenty-nine different neighborhoods, from the historic Gold Coast to the vibrant Pilsen and Chinatown districts. This unique loop provides a constantly changing backdrop of architectural styles and diverse community support, ensuring energy levels remain high throughout the 42.2 kilometers. The city also hosts the popular Bank of America Shamrock Shuffle 8K, a massive community race that kicks off the running season and utilizes the downtown parks.
Both major events start and finish in the heart of downtown, near Grant Park and Millennium Park. Whether you are tackling the full marathon distance to leverage the urban flatness for a speed goal, or enjoying a shorter race cheered on by thousands of dedicated Midwestern spectators, running in Chicago delivers an efficient, high-energy, and definitively world-class running adventure.
