Paris stars are back in action

Armand Duplantis and Letsile Tebogo headline a raft of Olympic champions who will descend on Lausanne for the first Diamond League meeting since the end of the Paris Games.

Some 18 current Olympic or world champions will be present in the Swiss city for today's meet, coming just 12 days after the last of the track and field action at the Stade de France.

Duplantis defended his gold in France's national stadium and improved his own world record to 6.25 metres.

Duplantis will be up against American Sam Kendricks, the silver medallist in Paris, and also Renaud Lavillenie, the 2012 Olympic champion and former world record holder who failed to qualify for what would have been his home Games.

"It's the only pole vault event next to a lake," Duplantis said.

"I love to have it scenic, fun, more like a show. It suits us well.
