The Bank of America Chicago Marathon draws thousands of runners from around the world - but the heroes aren't just the ones who finish first.
They're parents, siblings, coworkers, employees and more. They run for good causes, for personal records, for their health.
We asked our Facebook followers who their marathon heroes were and here's what they said. (Comment on the post linked here with your marathon hero if you would like to be featured!)

Silviano A. Gomez: Brónagh Tumulty is newer to this city. I find it very inspiring to see a person that is a local celebrity participating in something new, that is out of their normal comfort zone.
