It's about giving back
We’re proud to share that the Mackinac Island Swim is a fundraising event, with the Mackinac Woman’s Club as our primary beneficiary. In addition, we continue to support other causes that align with our mission throughout the year.
​
The majority of our fundraising takes place during registration—through optional donations—and on event day itself. Registration fees are intentionally structured to cover the costs of producing the event, including staffing, venue expenses, permits, insurance, medals, event swag, and social media and website operations.
​
Additional funds are raised during event weekend through a fundraising event hosted by the Mackinac Woman’s Club. This includes merchandise sales, raffles, and auction items, with proceeds benefiting the Mackinac Woman’s Club. Our sponsors play a vital role in these efforts as well, generously contributing time, financial support, and in-kind donations that help maximize the overall fundraising impact.
