Norway's Karsten Warholm ran a stunning men's 400m hurdles race to obliterate his previous world record and take gold at The Olympics.

Warholm, 25, finished in 45.94 seconds to slash more than seven tenths off his old record, having set the previous world record of 46.70 in Oslo in July.

Sportsworld’s Ed Harry caught up with Warholm and his coach on their way home from Tokyo.
