Norway’s Karsten Warholm broke Kevin Young’s 29-year-old 400m hurdles world record when he completed the race in 46.70 seconds in front of his home fans 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.
