100 metres Breaststroke, Men

Date	6 – 7 August 2016
Status	Olympic
Location	Estádio Aquático Olímpico, Parque Olímpico da Barra, Barra da Tijuca, Rio de Janeiro
Participants	46 from 38 countries

Britain’s Adam Peaty had won the 2015 World Championship and was the only swimmer to ever break 58 seconds in this event, with the second best performer over ½-second behind his personal best. The battle seemed to be for the other medals, and was felt to be contested by South African Cameron van der Bergh, the defending gold medalist, and Americans Kevin Cordes and Cody Miller.

That was exactly how the final worked out, as Peaty won gold in a stunning world record 57.13, winning by more than 1½ seconds over van der Bergh, with Miller winning a slightly surprising bronze, as he had not been heard from much before 2016. Peaty had actually broken his world record of 57.92 in the sixth heat, finishing in 57.55, then shattering that in the final. In all, he lowered the pre-Rio world mark by 0.79 seconds, a huge margin at this distance, and his record was 1.33 seconds ahead of the second fastest performer of all-time, van der Bergh.
