2ND ANNUAL CHICAGO RIVER SWIM

The Chicago River Swim presented by the City of Chicago and Mayor Brandon Johnson will return for its second annual event on Sunday, September 20, 2026, bringing swimmers back to the heart of downtown Chicago for another landmark civic moment. The inaugural Swim in 2025 marked a historic milestone as the first organized open water swim in the Chicago River in 98 years, demonstrating that the river can safely support large-scale recreational use while serving as a platform for environmental stewardship, public health, and philanthropy. The event is the result of more than a decade of persistence led by founder Doug McConnell, working in partnership with City leaders, scientists, and environmental organizations to make the return of swimming to the river possible. The City of Chicago and Mayor Brandon Johnson are serving as Presenting Partner, reflecting the City’s leadership in restoring the river and expanding safe public access to its waterways. Their support enabled an event of this scale to take place in the center of downtown, reinforcing the river’s transformation and establishing the Chicago River Swim as a growing civic tradition. The event is produced by nonprofit A Long Swim and founded by marathon swimmer and ALS advocate Doug McConnell. “Year one proved that this swim could be done safely and responsibly, and that people were ready to embrace the river in a new way,” said McConnell. “The second annual Chicago River Swim is about building on that momentum. It is deeply meaningful to see this become a lasting tradition that supports ALS research and helps ensure more young people have access to swim education and water safety.” Beneficiaries Proceeds from the 2026 Chicago River Swim will support ALS research as well as swim safety and swim education programs for youth in underserved communities. The Swim and Where to Watch On event day, qualified swimmers will take on one-mile and two-mile courses along the Chicago River’s main channel in downtown Chicago. The course, stretching from Wolf Point to State Street, will be marked by inflatable buoys and safeguarded by lifeguards, kayaks, and support boats. Spectators will be invited to gather along the Riverwalk and designated viewing areas to cheer on swimmers as they complete the course. More on the swim course can be found here.
