Armand “Mondo” Duplantis headlines a stellar cast in the Chinese city of Nanjing for the World Indoor Athletics Championships that were delayed thrice by the Covid-19 pandemic.

Nanjing was picked to host the biennial event back in 2020, then in 2021 and then again in 2023.

They were all moved due to coronavirus rules. In 2022 the event was instead held in Belgrade and in 2023 in Glasgow.

It now has the green light and Nanjing’s Cube will play host to 576 athletes from 127 countries competing in 26 events over three days of action from 21 to 23 March.

That number includes 11 individual defending champions — notably world record holders Duplantis (pole vault), Devynne Charlton and Grant Holloway (60-meter hurdles) — and 20 medalists from the Paris 2024 Olympic Games.

Duplantis, Holloway, Hamish Kerr (high jump), Thea Lafond (triple jump) and Miltiadis Tentoglou (long jump) followed up their Glasgow indoor successes with Olympic gold. They will be joined in Nanjing by fellow Olympic gold medalists Yaroslava Mahuchikh (high jump) and Jakob Ingebrigtsen (1500m and 3000m), also world record holders.

“I’m super excited,” Duplantis said.

“It was my first time competing in China last outdoor season for the first two Diamond League meets and I jumped extremely well, broke the world record, to 6.24m.”

The US-born Swede comes into the competition having bettered his world record — for the 11th time — to 6.27m at an indoor meet in the French city of Clermont on 1 March.

But Duplantis insisted there would be no recalibration of his season goals.

“No, not really,” he said.

“It’s not the first time I’ve broken the world record in the indoor season.”

“It’s according to plan right now, as far as I want.”

Duplantis said he knew he was capable of “higher heights,” insisting that he was “not fixated” by a certain height.

“It takes a little bit of time and it’s by fairly small increments — and it does get a little bit more difficult every time.”

“I’d like to get over 6.30m in the near future and then keep pushing it from there. Indoors is a great opportunity to break the world record because we don’t have to deal with the wind and whatnot so we have a lot more controlled variables in that sense.”
