Hyrox has grown to become one of the most hyped up sporting events in recent years.

But the buzz has been brought to a whole new level after Australian Hyrox athlete Joanna Wietrzyk went viral for pooping herself mid-race on Saturday (Sep 12) at the Hyrox event in Beijing. 

The 22-year-old suffered bowel incontinence midway through the Women's Pro event, but continued the race, even as clips circulating showed fecal matter visible on her leg. Joanna went on to win the race in the category. 

And according to his Instagram, Taiwanese singer Vanness Wu actually participated the very next day on Sep 13, just a day after Joanna.

Organisers said the venue had been thoroughly cleaned and disinfected following the poop incident, and relevant equipment was replaced before the event continued the next day. Yes, the same day the 48-year-old F4 member and the rest of the participants began the race.

It's said that Vanness and his teammates eventually crossed the finish line in 1 hour, 11 minutes, and 53 seconds.

Netizens, however, seemed a lot more interested in the venue's condition following the defecating incident, with many flocking to the comments to ask about it.

Some asked if he had "smelled" or "stepped on" the poo, while another remarked: "Hopefully you didn't get the poop stations".

A fan, however, joked: "The stadium smells really good today!" all thanks to Vanness' presence.

In response to the incident, organisers issued a statement, assuring that they have "clear biocontaminant and medical procedures in place".

"We recognise that this can understandably lead to frustration, questions and strong views within our community," they wrote.

"Those concerns are legitimate and, as organisers, we must be prepared to hear them, examine what happened and take responsibility for continuing to improve."

They, however, reminded there is no place in their community for "threats of violence or encouragement to harm an athlete", which has, according to them, happened over the weekend.

"Any person identified as engaging in this behaviour — whether through comments, direct messages or social media — will be permanently banned from all HYROX events," they warned.

They're also in the process of identifying those responsible before action will be taken.
