Aboutthe swim

The Mighty Mac Swim is an epic 4-mile swim across the beautiful Straits of Mackinac between Michigan’s upper and lower peninsulas, alongside the iconic Mackinac Bridge.  This celebrated annual event is both challenging and awe-inspiring! 

Internationally sanctioned by the World Open Water Swimming Association (WOWSA) and a member of the Global Swim Series (GSS), the Mighty Mac Swim has been placed prominently on the world stage. 

The Mighty Mac swim is held as a competition, but whether or not you wish to race, everyone who makes it across the Straits of Mackinac is indeed a champion!  Make no mistake, this is a “bucket-list” experience!

Mighty Mac Swimmers Are Pioneers

It was the Mighty Mac Swim which opened swimming the Straits of Mackinac to public participation. As recently as 2007, there were no more than 20 documented swims across these Straits.  Then on Labor Day of that year, in celebration of the 50th anniversary of the Mackinac Bridge, 50 made the crossing all at once as part of the first Mighty Mac Swim. Now, starting in 2019, four hundred swimmers will challenge the Straits of Mackinac in the Mighty Mac Swim each year!  ​

Mighty Mac swimmers continue to break down barriers and set new standards! 

If you complete the Mighty Mac Swim, you are indeed a PIONEER!
