The WC gold was secured when he sailed over six metres.
A moment later, "Mondo" flew over 6.21 in the second attempt and thus broke his own world record.
That's before the eyes of the coaching duo, as well as the parents, Helena and Greg Duplantis.
- It can't get any better, says Helena Duplantis.
What do you think when you see such a jump?
- It was incomparable.
There was air underneath!
Every time he goes and jumps I am impressed by what he does.
“World class!”
What are you most impressed with?
- That he can perform under pressure and that he is so level-headed.
You know where he is somewhere mentally and physically.
World class!
Greg Duplantis after the world record jump:
- It was amazing!
It's his best hope ever.
We made a small adjustment before the second attempt, changed the approach, and it was successful, he says.
