World records in sports are very difficult to make and even harder to defend...
2 men have almost single handedly dominated to Pole Valut game with 44 world records between them. Sergey Bubka made and bettered world record 35 times (18 times in outdoor competition and 17 times indoor). Now Armand Duplantis have already bettered his own world record 9 times..

What makes two men make and break world records like a routine ?
