Australian Kyle Chalmers set a short course world record in the men’s 100 meter freestyle when he won gold at the World Cup in Kazan, Russia on Friday.

Fresh after winning the 50 meter Freestyle on Thursday, the 23-year-old came home in 44.84 seconds, surpassing the 44.94 second mark set by Frenchman Amaury Leveaux in 2008.

The Russian Valdimir Morozov finished with just under 1.5 seconds Behind the second place ahead of his compatriot Kliment Kolesnikov in third place.

Chalmers won gold over 100 meters freestyle at the Olympic Games in Rio in 2016, but this year only achieved silver at the Games in Tokyo and ended up behind the American Caeleb Dressel.
