Australian HYROX athlete Joanna Wietrzyk has apologised after continuing to compete in the Beijing event on September 12, 2026, despite suffering sudden bowel incontinence during the race. She went on to finish first in the women’s Pro division, but later said she regretted not stepping off the track and has retroactively withdrawn from the race and forfeited the points she earned.
The controversy has also exposed a gap in HYROX’s event procedures. Co-founder Moritz Fürste acknowledged that organisers should have intervened immediately, while HYROX introduced rules allowing a Race Director to remove an athlete when blood, vomit, urine or faeces creates a welfare or contamination risk. The affected Beijing area and equipment were subsequently isolated and disinfected.
What happened during the HYROX Beijing race?
Wietrzyk, an Australian elite athlete and HYROX women’s solo world-record holder, competed in the Women’s Pro division at the Beijing event on Saturday, September 12.
HYROX is an indoor fitness competition in which athletes repeatedly alternate between 1-kilometre runs and functional exercises, including rowing, sled work, burpee broad jumps, sandbag lunges and medicine-ball movements. Several of the stations use shared equipment, making hygiene and contamination control particularly important when an athlete becomes physically unwell.
During the race, Wietrzyk experienced sudden faecal incontinence. Videos subsequently circulated on Chinese social-media platforms showing her continuing through the course despite visible contamination.
She did not stop and was not removed by officials. She completed the race and recorded the winning result in her division. The footage then spread internationally, prompting questions about both the athlete’s decision to continue and the organisers’ response.

Why the incident became a HYROX controversy
The central issue was not simply that an athlete became ill during an endurance competition. Gastrointestinal problems can occur in high-intensity and endurance sport, and athletes have previously competed through episodes of incontinence.
The distinctive problem in Beijing was that the incident occurred inside an indoor competition involving shared stations and equipment. Wietrzyk continued using those stations, while other competitors subsequently encountered the same competition environment. HYROX therefore faced questions about whether its procedures adequately addressed a contamination event occurring in the middle of a race.
Before the Beijing incident, HYROX rules already dealt with comparatively minor forms of contamination or course conduct, including penalties for littering, spitting and clearing the nose onto the course. According to ABC reporting, however, the rules did not contain an immediate provision specifically addressing faecal contamination.
That distinction matters because a rulebook does more than determine whether an athlete receives a penalty. In a mass-participation indoor sport, it also establishes when officials should prioritise the safety and hygiene of competitors over continuation of an individual race.
HYROX admits it should have intervened
HYROX co-founder Moritz Fürste subsequently apologised to people affected by the incident.
Fürste said HYROX had made a mistake by not reacting immediately during the race and accepted responsibility for failing to anticipate the situation. He said new rules and procedures had been introduced to prevent a similar incident from happening again.
The updated provision states that a Race Director may withdraw a competitor on medical grounds when the athlete’s blood, vomit, urine or faeces presents a welfare or contamination risk to the athlete or other racers.
HYROX World also said that protocols intended for elite competition and mass participation had become blurred, creating ambiguity over how they should be applied. That explanation is significant because it points to a procedural problem rather than suggesting the Beijing incident was covered adequately by an existing rule.
What happened to the contaminated area?
HYROX China said the affected section was isolated and comprehensively disinfected. Contaminated equipment was removed, while reporting from the Guardian said the venue carpet was replaced overnight before competition resumed.
Those measures indicate that organisers treated the incident as a contamination event after the race. The unresolved question at the centre of the controversy was why equivalent intervention did not occur while the race was still underway.
Joanna Wietrzyk apologises and gives up the result
Wietrzyk addressed the controversy publicly on September 17, five days after the race.
She said she had felt completely fit and healthy at the start of the competition and had no reason to expect an illness. In retrospect, however, she said she regretted not stepping off the track and accepted responsibility for continuing.
She apologised to people in China, fellow competitors, spectators and HYROX organisers, and said the incident had affected people beyond herself.
Most significantly for the competition record, Wietrzyk announced that she would retroactively withdraw from the Beijing race and forfeit the points she earned.
That changes the sporting status of what initially appeared to be a race victory. The result may have existed on the day, but Wietrzyk’s subsequent withdrawal means she no longer accepts the result as part of her competitive record.
The controversy involves two separate responsibilities
The Beijing episode has generated criticism of both Wietrzyk and HYROX, but those are distinct questions.
The athlete’s decision: Wietrzyk has acknowledged that she should have stopped racing once the incident occurred. Her later withdrawal and apology directly address that decision.
The organiser’s responsibility: HYROX has acknowledged that officials should have intervened and has changed its rules to give Race Directors explicit authority to remove athletes when bodily-fluid contamination creates a welfare risk.
Keeping those responsibilities separate is important. An athlete’s decision to continue does not eliminate an organiser’s duty to operate a safe competition environment, while an organiser’s failure to intervene does not necessarily remove an athlete’s own responsibility for decisions made during a race.
Why HYROX’s rule change matters beyond Beijing
The incident highlights a broader challenge for rapidly expanding sports: procedures designed around ordinary competition can fail when an unusual medical or hygiene situation develops in real time.
HYROX has grown from a relatively specialised fitness competition into an international mass-participation sport. The Beijing event was part of a rapidly expanding Chinese market; ABC reported that HYROX’s first mainland-China event in November 2024 attracted fewer than 1,700 contestants, while average registrations had risen to 5,079 per event in 2025.
As participation grows, unusual events become operational problems rather than merely exceptional athletic moments. Officials need clear authority to stop a competitor, isolate equipment, protect subsequent racers and communicate what has happened without creating unnecessary confusion.
The updated contamination rule therefore addresses a practical issue that extends beyond this particular incident: when continuing a race could expose other competitors to a preventable health or hygiene risk, officials need an unambiguous basis for intervention.
What remains unresolved
HYROX has acknowledged the officiating failure and changed its rules, while Wietrzyk has apologised and surrendered the points from her Beijing result. Those are concrete responses to the incident.
What remains less clear is how the new procedures will work operationally at future events. A rule allowing a Race Director to withdraw an athlete is only as effective as the officials’ ability to recognise a contamination risk, intervene quickly, isolate affected areas and communicate with competitors.
The Beijing controversy therefore may prove more significant as a test of HYROX’s event-management standards than as a story about one athlete’s race. The lasting measure will be whether the new procedures remove the ambiguity that HYROX itself identified—and whether future competitors can expect medical and contamination incidents to trigger immediate, consistent action.
