When you think of Hyrox, you might remember of those viral pictures of an athlete pushing through the race even though diarrhoea was running down her legs.

Her name is Joanna Wietrzyk - and in an exclusive interview with the BBC, she’s described the fallout after she won the competition. She and Hyrox have previously apologised. She’s spoken to the BBC now about the online hate she got after the race (we’ve put the link to that interview at the bottom for you).

It catapulted the fitness craze into the spotlight - but now it’s making headlines again, because of its bid to become an Olympic sport. So how has Hyrox got so popular - and does it have a good chance of making it into the Olympics?

BBC Health reporter and Hyrox athlete Annabel Rackham explains why Hyrox is taking off in a big way. BBC journalist Jacob Evans - who has also just done his first ever Hyrox - shares his experience, and explains some of the difficulties the sport could face in its Olympic bid. And sports journalist Emma Sunny tells us what she think this means for the world of sports more widely.

Also — the Olympics has a long history — which including sports that you might not expect. We put Hannah to the test to see if she can guess which sports have made an appearance over the years.

Kylian Mbappé - the French football superstar sometimes nicknamed a ‘Dictator’ online - has found himself at the centre of a scandal in China this week, after mentioning one of the memes made about him. It shows his face on the body of Mao Zedong, the former Chinese leader, and on a French talk show, when Mbappé describes it, he refers to Mao as a dictator.

The backlash against Mbappé has been huge. He’s been dropped by major Chinese brands, shops have pulled football shirts with his name off the shelves, and the state broadcaster has even stopped showing La Liga matches. Mbappé, Real Madrid and La Liga - the Spanish league - have all apologised.

So how did a joke about meme become so controversial in China - and what does it tell us about censorship in the country? Kerry Allen, the BBC’s China Media Analyst, talks us through it all - and we hear from the BBC Global China Unit’s Shawn Yuan, who explains how censorship in China is changing.
