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
As recently as 2007, there were no more than 20 documented swims across the Straits of Mackinac. 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. Incredible! Now, starting in 2019, four hundred swimmers will challenge the Straits of Mackinac in the Mighty Mac Swim each year!
Oh, how we have grown! Oh, how we have broken down barriers!
If you complete the Mighty Mac Swim, you are indeed a PIONEER!
The Straits of Mackinac is Open for Swimmers!
Once open to only a select few, the Mighty Mac Swim now safely
accommodates a maximum of 400 swimmers for just a $375 entry fee.
It has been said that we have set a new industry-wide standard for safety in
an otherwise often treacherous open water venue.
