Tri for a Cure is Maine’s only all-women triathlon and also the largest triathlon in the state.

But this is so much more than a race. It truly is a celebration of hope, determination, and courage as women raise millions of dollars to fight cancer in Maine while supporting each other and amazing themselves. I've done a leg of this triathlon a couple of times in my life. There is nothing more inspiring than this day.

For the first time in the history of the Tri, registration was on a FIRST COME FIRST SERVE  basis. It sold out quickly.
