Masters swimming is a fast-growing leisure activity, particularly in North America and Australia but also in Europe. Most towns or cities now have masters clubs. Typically these are very friendly and welcome newcomers. The minimum requirements to join a masters club vary widely, anywhere from the ability to swim one length of the pool to the ability to swim a kilometre without stopping. Club members will follow a set of different drills and swims each time typically covering anything from 1.5 km to 3.5 km per one-hour session. Each club will have lanes and so whilst the younger and faster swimmers who are competing nationally and regionally are at one end, the other lanes are for hobbyists who may have taken up swimming quite recently.
