Olympic and world champion Mondo Duplantis has broken the pole vault world record 15 times and utterly dominated the event, but Greece’s Emmanouil Karalis has now emerged as a real challenger having found the courage to go toe-to-toe with the Swede.

The pole vault has had a familiar feel in recent years. Duplantis wins the competition before going after his own world record, but there are signs that his one-man era could be at an end.

At Thursday’s Zurich Diamond League, Karalis and Duplantis both attempted to beat the world record for the first time in the same competition.
