Each year, over 1,300 women gather in South Portland to swim, bike & run in Maine Cancer Foundation’s Tri for a Cure - Maine's largest fundraising triathlon. Thanks to the efforts of thousands of supporters, the Tri for a Cure has raised almost $22 million for Maine Cancer Foundation, every dollar of which has been reinvested into Maine communities for cancer prevention, early detection, and access to care. Cancer tries, but we TRI harder!

Details get you ready for the 2024 Tri for a Cure!


The Tri for a Cure is only possible with the generous support of our sponsors. Because the costs of executing the race are covered by sponsors, every dollar raised by participants is invested across Maine, providing dollars to support cancer prevention, screening, and access to care throughout the state. Sponsoring the Tri for a Cure represents a triple-win for local businesses: an excellent chance to give back to your local community, a fun and exciting fitness event for your employees, and broad publicity across many channels recognizing your support.
