Australian HYROX athlete Joanna Wietrzyk, the world No.1-ranked women's singles competitor, has issued a public apology and announced she is retroactively withdrawing from a race in Beijing after footage of her competing while visibly soiled went viral, sparking widespread outrage across the sport.

The 22-year-old was competing in the Women's Pro division in the Chinese capital at the weekend when she defecated during the event. Despite the incident, race organisers permitted her to continue, and she ultimately crossed the finish line first. Graphic footage that circulated widely online showed faecal matter smeared across her arms and legs as she raced.

Wietrzyk's Instagram apology and decision to forfeit

One week after the Beijing event, Wietrzyk published a four-paragraph statement on Instagram, expressing remorse for what had occurred and acknowledging she should have stepped off the course.

"I want to offer my sincere apology to the people of China, my fellow competitors, the spectators and the HYROX organisers for what happened during the race in Beijing," she wrote. "I felt completely fit and healthy at the start of the race, with no reason to expect any illness. Looking back, I regret the decision to not have stepped off the track. I recognise that I should have made a different choice. I take responsibility for my decision to continue and am deeply sorry for the discomfort and disruption it caused."

Wietrzyk also confirmed she had chosen to give up the result entirely. "I know my actions had an impact beyond myself, and I am genuinely sorry to everyone who was affected," she wrote. "On reflection, I have decided to retroactively withdraw from the race and forfeit the points I earned."

The athlete closed her statement by thanking supporters who had reached out with kindness, and said she would be taking time away from competition to recover and reflect. "I will be taking some time to recover, reflect and look after myself and my family away from the noise," she wrote.

HYROX organisers condemned online threats and admitted fault

The fallout extended beyond Wietrzyk herself. HYROX organisers issued a statement condemning a wave of online threats directed at athletes in connection with the incident, warning that anyone found to have made such threats would be permanently banned from future events.

HYROX co-founder Mo Furste later stepped forward with his own apology, admitting the organisation had made an error by not intervening at the time and removing Wietrzyk from the race. Furste confirmed that new rules and procedures had since been put in place to ensure a similar situation would not arise again.

What is HYROX?

For those unfamiliar with the discipline at the centre of the controversy, HYROX is a global indoor fitness racing format launched in Germany in 2017. The sport has grown rapidly into a worldwide phenomenon, attracting thousands of participants who compete on a closed, indoor circuit designed to test both strength and endurance.

A defining feature of HYROX is that every course layout and workout is identical across all global events, meaning athletes can directly compare their finish times against competitors from around the world on a unified leaderboard — a structure that sets it apart from formats such as marathons or obstacle course races.

What happens next for Wietrzyk

With her points forfeited and a period of personal reflection underway, Wietrzyk's immediate competitive future remains unclear. The incident has, however, prompted meaningful structural changes within HYROX itself, with the organisation now bound to its newly introduced protocols should a comparable situation occur at future events.

As world No.1, Wietrzyk's standing in the sport will inevitably be watched closely when she does return — and how both she and HYROX's leadership handle the aftermath may well define the next chapter for the rapidly growing fitness competition circuit.
