Warholm destroys world record to win men's Olympic 400m hurdles gold

A world record had been predicted but Norway's Karsten Warholm did not just break it, he destroyed it to hold off American Rai Benjamin and win a superb men's Olympic 400 metres hurdles final on Tuesday.

Last month, Warholm broke Kevin Young's 29-year world mark with a time of 46.70 seconds but he blew his own record away with an astonishing 45.94 run, reports Reuters.

Benjamin pushed him all the way to take silver in 46.17, also half a second inside the old record.

Brazilian Alison dos Santos got in on the act as well as he took bronze in 46.72, also inside Young's previous best.
