Masters swimming is simply the name some people use for adult swimming.

The term originated in the USA in the 1970s when some former swimming champions organised a competition for adult swimmers. Nowadays, Masters swimming refers to any kind of swimming for adults, from casual fitness swimming to competitive swimming. You don't have to be a former elite swimmer, you just need to enjoy swimming.

To qualify as a Masters swimmer you need to be at least 25 years of age. Some swimming clubs have Masters sections and a few swimming clubs are dedicated to Masters alone.
