Chicago Yacht Club Race to Mackinac in Chicago
The Chicago Yacht Club Race to Mackinac, known as the Mac, is a 333-mile offshore sailboat race from Chicago's Lake Michigan shoreline to Mackinac Island, Michigan. First run in 1898 and hosted by the Chicago Yacht Club, it is the oldest annual freshwater distance race in the world, typically held in mid-to-late July, drawing several hundred boats and several thousand sailors rather than festival-style spectator crowds.
Its age and Great Lakes endurance identity make it a major sports/adventure row.
