Marchand won in 1min 54.06sec, the second-fastest time in history and an Olympic record. He adds this gold to 200m butterfly and 200m breaststroke ones, along with the 400m individual medley. To the opening 400m freestyle title, Marchand was able to add on Wednesday the feat of combining the 200m butterfly and 200m breaststroke on the same night. 

Britain's Duncan Scott (1:55.31) took silver and China's Shun Wang (1:56.00) bronze in Friday's final. China's Wang, the defending champion, led after the opening butterfly leg.

Australia

It was another successful evening for Australia as Kaylee McKeown won gold in the 200 backstroke ahead of Regan Smith of Team USA and Canada's Kylie Masse achieving an Olympic Record in the process.

McKeown successfully defended her title in an Olympic record 2min 03.73sec ahead of American Regan Smith (2:04.26) and Canada's Kylie Masse (2:05.57) with victory in the 200m to go with her 100m title in Paris. No Australian swimmer, male or female, had ever completed the 100-200 backstroke double at consecutive Olympics.

Australia's Cameron McEvoy won the 50m freestyle gold medal in the Paris Olympics on Friday adding a new medal for his country.

Australian swimmer Cameron McEvoy claimed his first Olympic gold. McEvoy, the 2023 world champion in the event, won with a time of 21.25 seconds, followed by Great Britain's Benjamin Proud (21.30) and France's Florent Manaudou (21.56). For Manaudou, it is the fourth consecutive Olympic Games in which he has won a medal in the shortest freestyle event. He won gold at London 2012 and silver at Rio 2016 and Tokyo 2020.

McEvoy competed in three Summer Olympics, between 2012 and 2020, winning three medals, two bronze medals at Rio 2016, in 4 × 100m freestyle and 4 × 100m freestyle, and bronze at Tokyo 2020, in 4 × 100m freestyle.
