Mondo Duplantis made his feelings known about winning the 2025 World Indoor Champion title
Mondo Duplantis once again proved his billing in the 2025 World Indoor Championships after winning consecutive gold medals in pole vault at the 2022 Belgrade World Indoor Championships and the 2024 Glasgow World Indoor Championships. After bagging his most recent gold medal in Nanjing, he engaged with BBC Sport for a post-event interview, where he was asked about how he felt about his performance and the win.
Duplantis revealed that he was feeling tired while he was on the runway and was constantly pushed by his contender, Karalis, during the showdown.
"It took a lot out of me, for sure. I felt a little bit sloppy on the runway, a little tired, a little heavy, honestly. Karalis was pushing me like crazy.The highest loser ever in the history of pole vaulting - that's a testament to the level of competition here today," said Mondo Duplantis.
He further said,
"That took a lot out of me. It's been super fun. Today was tough. I think we're going to see some crazy competitions in the future soon."
Mondo Duplantis currently holds the world record in the pole vault event, as he clocked 6.27 m at the All Star Perche event in Clermont-Ferrand, France, on February 28, 2025. It was the 11th time that the 25-year-old had broken the world record.
