Dive into Marathon

Course:

  • Main Swim: From Sharps’, around the outside of Pig Island, to the Main Dock

Ready to make a splash?

Whether you’re chasing Olympic dreams, aiming for a personal best, or simply enjoying a relaxed head-up doggy paddle while chatting with friends, everyone is welcome. The goal is simple: PARTICIPATION!

One of the best parts of this event is seeing swimmers of all ages join in. We’ve had an amazing range of participants over the years, and every swimmer earns a well-deserved chocolate bar at the finish line.

Not planning to swim? We’d love to have you out on the water anyway! Spotters in canoes, kayaks, or other small watercraft are always appreciated to help cheer on the swimmers—and yes, spotters get a chocolate bar too!

We can’t wait to see both familiar and new faces on the water for another great Mad Marathon!
