Swimming is much more than an Olympic event. According to 2017 data 27 million Americans swim for fitness. Similar data is reported from English cities where more than 4 million men and women's swim at least once a month. USA Swimming, the national governing body for the sport in the United States, has 400,000 members and 2800 teams in the country.
