Hyrox athlete Joanna Wietrzyk apologises and withdraws after competing with faecal incontinence

Earlier, Hyrox said anyone sending abuse or threats of violence towards the athlete would be banned from any future events after her identity was shared online.

"There is no place in our community for threats of violence or encouragement to harm an athlete," Hyrox said in an earlier statement on Monday.

"Any person identified as engaging in this behaviour - whether through comments, direct messages or social media - will be permanently banned from all Hyrox events," it said.

Delving into how the incident played out, the German sports brand insisted it had "clear biocontaminant and medical procedures" in place.

It said "an unforeseen situation arose" during which protocols became blurred, "creating ambiguity in how they were applied and understood".

Following Saturday's event some participants had demanded an apology and a refund, arguing that they were forced to come into contact with contaminated equipment, Chinese media reported.

Joe Ho, who took part in the Hyrox Beijing competition over the weekend, criticised its response to the issue and called on the organisation to "take responsibility when its own procedures fail".

"If the organisation accepts that something went wrong, why not offer affected participants refunds, credits, or some meaningful form of compensation?" he wrote.

Anthony Huang, associate professor in the Department of Sport Information and Communication at the National Taiwan University of Sport, told BBC Chinese that incidents such as these could reflect a "results-driven attitude" within the rapidly growing sports brand.

"The idea that 'a win is a win' represents a results-driven view of competition, but a mature sporting culture can't just ask whether you won - it also has to ask how you won," he said.

He added the incident raises questions over Hyrox's business model and whether commercialisation may be outpacing its ability to manage the sport.
