Norway’s Karsten Warholm broke Kevin Young’s 29-year-old 400m hurdles world record when he completed the race in 46.70 seconds at the Diamond League meeting in Oslo on Thursday.
Warholm beat 1992 Olympic champion Young’s mark of 46.78secs, which was set four years before the Norwegian was born and was the longest-standing record in men’s track.
Twice world champion Warholm raced to an early lead and never let up as he was roared on all the way to the finishing line, which he crossed ahead of 2019 Pan American Games champion Alison dos Santos by more than six tenths of a second.
