The 117th Chicago Yacht Club Race to Mackinac — the world's largest offshore freshwater race.
The Race to Mackinac is a Chicago summer institution — the world's largest and oldest annual offshore freshwater race. Hundreds of boats and thousands of sailors line up off the lakefront before setting off on the 333-mile run up Lake Michigan to Mackinac Island. The send-off from the shore is a spectacle of sails as far as you can see.
Good to know: Watch free from the lakefront near the harbors. Bring binoculars and sunscreen; arrive early for the best vantage points.
