Why run it?

Part of the World Marathon Majors, running the Bank of America Chicago Marathon is the pinnacle of achievement for elite athletes and everyday runners alike. The race starts and finishes in Grant Park, and travels through one of the world’s most magnificent cities. With ideal weather conditions, dry with highs of 67°F (19°C), this marathon is an unmissable and highly in-demand event.

Please note, as realbuzz is an international partner of the Bank of America Chicago Marathon, we will not be able to offer places to US residents.
