Norway's Karsten Warholm has broken the men's 400m hurdles world record.
He did it in front of home fans at the Oslo leg of the Wanda Diamond League on Thursday afternoon with a time of 46.70 seconds.
The previous record, which stood for 29 years, was set by American Kevin Young when he ran a time of 46.78s at the Olympic Games in Barcelona, Spain in 1992.
Warholm, 25 years old, said it could take another world record to win at the Olympics, in Tokyo, starting later this month.
"I knew that I had a fast time in my body," he said. "It feels like it has been there for a long time, but you never know when it is right to do it.
"And it is one thing to know you have it in you, and another to go out and do it.
"There are such a lot of great guys out there at the moment who will all be aiming to do it and win gold."
Seven of the 15 fastest 400m hurdles times ever recorded belong to Warholm.
Jamaica's Jaheel Hyde, Kemar Mowatt, and Leonardo Ledgister are set to compete in the 400m hurdles with Warholm in Tokyo on July 30.
