The Mac Solo Challenges consist of the Port Huron to Mackinac Island Challenge (230 nautical miles), the Chicago to Mackinac Island Challenge (287 nautical miles), the Super Mac (517 nautical miles), and the Super Mac and Back (1034 nautical miles). The Challenges are held annually, generally taking place on the third or fourth Saturday in June. These two Challenges, run concurrently, and feature a common finish line at Mackinac Island. The President’s Cup Trophy is awarded to the first time finisher on each lake who has the fastest corrected time. An awards luncheon takes place on Mackinac Island on the Wednesday following the start of the Challenges, and non-member skippers who successfully complete either Challenge will be awarded lifetime membership in the Society.
