Whether you are a competitive swimmer looking for a great training opportunity, or a recreational swimmer who cares about clean water, you can feel good knowing that your registration makes a difference to help protect our lakes. Choose from a 1.2 or 2.4 mile event in the same waters as the Ironman swim course.
