    • Please understand that rela​y members will be responsible for transporting themselves around the island.  Remember, there are no vehicles on Mackinac Island, which means relay teams will either need to walk/run or bicycle to meet their relay members.  From it's furthest point to town (start/finish line) members may be responsible to cover up to 3.6mi on foot.

    • Relay teams of more than 4 will need to develop a transition plan for each relay exchange and have it approved by an event director.

    • Specific relay exchange points are offered and mandatory to use as exchanges during this swim.  Please have at least 1 swimmer able to swim up to 3 miles at once.  More information about the relay exchanges can be found in the "Event Maps" section of this website.

    • This means bring SHOES

  • STAYING ON THE ISLAND THE NIGHT BEFORE THE EVENT IS NOT NECESSARY.  Sheplers Ferry has agreed to offer an early service for swimmers the morning of the event.  You will be responsible for purchasing a ferry ticket and being on this ferry in order to make it to the start of the finish line.

It's about giving back

We are proud to announce that The Mackinac Island Swim is completely a fundraising event.  ALL profits go to benefit the local community.  The Mackinaw Woman's Club, will be our main benefactor.  However, we will also be fundraising for other local organizations throughout the event and leading up to it.  Our registration fee was designed to pay for the expenses of the swim itself (staff expenses, permits, insurance, event swag, medal, this website, etc.) and the goal of raising at least $20,000 for local charities.
