Who Is Joanna Wietrzyk? Viral Hyrox Athlete Who Pooped Herself While Competing

Joanna Wietrzyk has become the centre of online attention after a highly unusual incident during the HYROX Pro event in Beijing on 12 September 2026.

Videos circulating on social media appeared to show the Australian athlete suffering a bowel-control incident during the race, with visible faecal matter on her legs as she continued through the course. She completed the event despite the incident and went on to win the women's Pro race in 1:01:23.

The footage quickly spread online, prompting debate about hygiene, safety and whether officials should have stopped her from continuing. HYROX subsequently undertook cleaning measures, while the incident generated widespread discussion beyond the sport's usual audience.

Wietrzyk later addressed the episode on social media. A post included the phrase 'a win is a win', while she also thanked supporters. However, the full context of her comments has not been independently established.

The controversy has overshadowed what was otherwise another significant result for one of HYROX's fastest-rising athletes.

Personal Life, Family and Sporting Background

Wietrzyk is an Australian athlete from Melbourne, Victoria. Public profiles have listed her as 22, although age references can change as biographical information is updated. She previously competed in tennis at national level and later played netball at state level.

She was also studying for a Bachelor of Commerce at Deakin University, majoring in marketing, while working as an F45 coach in Melbourne. It was through the gym community that she discovered HYROX. She has said that she initially knew very little about the sport before members and fellow trainers encouraged her to enter.

Details about Wietrzyk's wider family are limited in reliable public sources. Her mother has, however, featured prominently in accounts of her career. After Wietrzyk's record-breaking performance in Warsaw in April 2026, her mother was reportedly present at the finish after returning to her home city for the first time in about 15 years. Wietrzyk described the moment as something she would remember forever.

There is no reliable public information confirming that Wietrzyk is married or identifying a current boyfriend or partner. Her relationship status therefore remains private.

Career, World Records and What's Next

Wietrzyk's HYROX rise has been remarkably quick. She began competing in 2024 and soon became the first Australian woman to qualify for the Elite 15 series. She also finished second at the 2025 HYROX World Championships.

In 2026, her career reached another level. She won the Phoenix Major before setting the women's Solo Pro world record at the Warsaw Major in April with a time of 54:25.08. The performance was the first women's HYROX finish under 55 minutes.

She subsequently became the first athlete to win all four Elite 15 Majors in a single season, according to recent coverage of her 2025-26 campaign.

Her focus now is expected to remain on elite HYROX competition and improving an already record-breaking standard. Wietrzyk has previously suggested that a women's time below 52 minutes could be possible within the next few years.

The Beijing controversy has brought unprecedented attention to her. But behind the viral moment is an athlete who, in just two years, has progressed from F45 coaching in Melbourne to becoming the fastest woman in HYROX history.
