The Australian women crushed their own 4 x 100 free relay world record tonight, winning the gold medal in a 3:30.65.
The Campbell sisters led the way, with anchor Cate splitting 51.97, and third leg Bronte splitting 52.15, both faster than anyone in the field.
The Australians have held the world record in the 4×100 free since 2014, when they took down the 3:31.72 set by the Netherlands at the 2009 World Championships in Rome. Three of the four team members from tonight were also on the previous world record relay: Cate Campbell, Bronte Campbell, and Emma McKeon. Below see the world record split progression:
|World Record||Swimmer 1||Swimmer 2||Swimmer 3||Anchor||Time|
|2014 AUS||Bronte Campbell: 53.15||Melanie Schlanger: 52.76||Emma McKeon: 52.91||Cate Campbell: 52.16||3:30.98|
|2016 AUS||Emma McKeon: 53.47||Brittany Elmslie: 53.12||Bronte Campbell: 52.15||Cate Campbell: 51.97||3:30.65|
The Australian team came in a full second ahead over the second-place Americans and nearly two ahead of the third-place Canadians.
Cate and Bronte will both take on the 100 free later this week, where they come in heavy favorites to both medal, if not to sweep first and second.
