Karsten Warholm broke the world record in the men's 400m hurdles in front of a home crowd at the Diamond League track and field athletics meeting in Oslo, Norway, on Thursday (1 July).
The 29-year-old record of Kevin Young was finally broken with an official time of 46.70s.
The American’s mark of 46.78 seconds was set at the 1992 Olympic Games in Barcelona, Spain.
It sets up an intriguing match up at the Monaco Diamond League meeting where both Warholm and rival Rai Benjamin of USA are scheduled to go head-to-head on July 9.
The record comes after the women’s 400m world record was also recently broken by the USA’s Sydney McLaughlin at the 2021 U.S. Olympic Track and Field Trials.
