The Swede cleared the new world record height on the second attempt after already having secured the victory at the competitions in Budapest.
Earlier in the summer, on June 15 at the competitions at Stockholm Stadium, Duplantis set a world record at home – then 6.28.
It felt pretty crap today and I really wanted to jump a world record. Ah, I pushed so hard. It was all I had in me. I'm really happy that I managed it, he said in an interview on the infield directly after the record.
The new world record of 6.29 is Duplantis' 13th world record in pole vault. The win in the competitions in Budapest is at the same time the Swede's 32nd consecutive victory. It's been over two years since the 25-year-old lost a competition.
