The Chicago Marathon is one of six World Major Marathons, and this year will host around 50,000 runners from around the world, not to mention the spectators, vendors, and volunteers. So, is it possible for an event of this magnitude to be sustainable? On this episode, Casey and Sara chat with Cat Morris, the Sustainability Manager at Chicago Event Management, overseeing the Chicago Marathon. Hear about how the Chicago Marathon became certified as an Evergreen Inspire event through the Council for Responsible Sport, how waste, from water cups to gel packets, is being diverted from landfills, and how runners and spectators can get involved!   Sara will be running the 2024 Chicago Marathon as part of Team Fox, raising funds for the Michael J Fox Foundation for Parkinson's Research. If you'd like to donate to support the Foundation's work to find a cure for Parkinson's, you can donate through Sara's fundraising page here: https://give.michaeljfox.org/fundraiser/5270913   Resources for this episode:  Chicago Marathon Sustainability Community Impact through Compost: Chicago Distance Series Instagram: Tina Muir, Chicago Marathon Sustainability Ambassador Instagram: Chicago Marathon Know Before You Go: Sustainability
