Chicago Riverwalk | Chicago, IL 7:00 AM
Time to dust off your goggles, Chicagoans—for the first time since the Roaring Twenties, you can legally take a dip in the Chicago River. Chicago River Swim will host 500 swimmers in the Chicago River's green-tinged waters for a race benefitting ALS research at Northwestern University, youth swim education in underserved communities and programs aimed at closing the racial gap in swim access. For spectators, the Riverwalk between Lake and Clark streets will transform into a festive viewing area, with food, drinks and a VIP party for those who prefer a fancier vantage point.
