It’s not just the economic numbers from the Bank of America Chicago Marathon that that are compelling.

Indeed, the 2023 race contributed $547 million to the city’s economy, notes a study conducted by Jones & Associates Economics. That means the financial effect of the race — which was $386 million in 2022 — increased by a whopping 42% increase in just one year. And over the last seven years, the Bank of America Chicago Marathon has had a cumulative economic impact on the Chicagoland region of over $2.3 billion.

But there are other figures that tell a similarly engaging story about the Chicago Marathon, which was first held in 1905, discontinued in the 1920s, then restarted in 1977. Here’s a look at some of the Bank of America Chicago Marathon numbers from over the years:
