The course from above
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
majestic 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!
"Finheads" Pioneered Straits of Mackinac's Evolution
into Premier Open Water Swimming Venue
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. Incredible! But, that was just the start. Skip ahead to 2019 ... when an amazing four hundred swimmers churned the waters and challenged the Straits of Mackinac in what has now become an annual Mighty Mac Swim spectacle!
Oh, how we have grown! Oh, how we have broken down barriers!
The Straits of Mackinac area is rich in history involving Native American inhabitants, French settlers, fur
traders, missionaries, British & American fortresses and the building of a bridge which once seemed
inconceivable. "Finheads," as Mighty Mac swimmers are affectionately called, have raised the bar and
introduced to the masses a once unthinkable alternative to crossing the Straits via the bridge spanning
above them ... a more romantic way, fueled by adrenaline. Finheads now have a place in Straits of
Mackinac historical lore!

Priority Registration: 2021 registration opens for returning 2020 swimmers 48 hours before public registration. Registration for waitlisted swimmers opens 24 hours before opening to the public. Waitlisted swimmers who serve as an event volunteer will be bumped up to 48-hour priority status with the returning swimmers.
Volunteering & Waitlisted Swimmer Incentive
Experiencing the Mighty Mac Swim as a volunteer is also
unforgettable and rewarding! If you are interested in learning
more about volunteering, please click the “Sign Up” button on
the page header. When you land on the RunSignUp page, click
the “Volunteer” tab and check out the opportunities! We are
looking for general volunteers to serve in a variety of ways,
in addition to kayakers, lifeguards and more. We use the term
“volunteer” generically, as some are paid positions. We would
love to have you on our team!
If you sign up to volunteer, you may refer back to the RunSignUp
Volunteer page anytime for a refresher on volunteer details.
Prior to the event, an informational document with full agenda
and detailed procedural instructions will be emailed to you.
Waitlisted swimmers who agree to be removed from the waitlist in favor of volunteering, will be guaranteed 48-hour priority registration status for 2021, along with returning 2020 swimmers. This means volunteers, formerly on the waitlist, will be given 48 hours to register before public registration opens and 24 hours before the waitlisted swimmers are given an opportunity to register. Swimmers on the waitlist will likely sell out the event before registration ever opens to the public.
All registrations are accepted on a first-come-first-served basis, but if you accept this offer for top priority registration status, your entry will be all but guaranteed. Let’s do the math. We need approximately 100 volunteers. Generally, 25% - 50% of the 400 swimmers return the following year, meaning it is likely no less than 200 entries will be available to no more than 100 volunteers.
Volunteering is a great way to see what the Mighty Mac Swim is all about while assisting others in reaching a “bucket list” goal!
Volunteers are the lifeblood of the Mighty Mac Swim. THANK YOU for transfusing your energy into one of life’s great experiences!
