Similar to the program's format in 2012, swimming features a total of 34 events (17 each for men and women), including two 10 km open-water marathons. The following events will be contested (all pool events are long course, and distances are in metres unless stated): Freestyle: 50, 100, 200, 400, 800 (women), and 1,500 (men); Backstroke: 100 and 200; Breaststroke: 100 and 200; Butterfly: 100 and 200; Individual medley: 200 and 400; Relays: 4×100 free, 4×200 free; 4×100 medley Marathon: 10 kilometres The swimming competitions at the 2016 Summer Olympics in Rio de Janeiro took place from 6 to 13 August at the Olympic Aquatics Stadium. The women's open-water marathon was held on August 15, and the men's open water race on August 16 in Fort Copacabana.[1] The location for open-water events was a source of concern for athletes since scientists have found microbes in the waters off of Fort Copacabana and drug-resistant super bacteria off the beaches of Rio de Janeiro in 2014 and 2016 studies due to the daily dumping of hospital waste and household raw sewage into the rivers and ocean. Ten percent of the Copacabana water test samples contained drug-resistant super bacteria.[2][3] However, during the races the water quality was good. -~-~~-~~~-~~-~- Please watch: "Michael Phelps training ✪swimming tips ✪ live part 3" https://www.youtube.com/watch?v=NoMZ-tOdGUU -~-~~-~~~-~~-~-
