Carthage offers a training program for masters swimmers and triathletes. The coached workouts focus on drills as well as distance and speed.

The Master’s Swim Team is broken into two ability groups and gears the workouts to the abilities of the group. One group, the “Sharks,” is your very competent, perhaps ex-college swimmers. The other group, the “minnows,” are typically triathletes who are not gifted swimmers, and trying to build endurance and speed for triathlons. Every ability is welcome!
