Australian HYROX athlete Joanna Wietrzyk has apologized and retroactively withdrawn from HYROX Beijing after experiencing bowel incontinence during the race and continuing to compete. The incident has also prompted HYROX to strengthen rules covering athlete welfare and contamination risks.
Australian HYROX athlete Joanna Wietrzyk has apologized for continuing to compete after experiencing sudden bowel incontinence during the HYROX Beijing 2026 Women’s Pro race.
Wietrzyk competed on September 12 and initially crossed the finish line first in 1:01:23, ahead of reigning HYROX world champion Alyssa McElheny, who finished in 1:02:08.
However, the result was quickly overshadowed by an incident during the race in which Wietrzyk experienced bowel incontinence but continued through the indoor competition.
Footage from the event circulated widely on social media, prompting discussion about athlete welfare, hygiene and the responsibility of race officials to intervene when a health or contamination issue develops.
Wietrzyk later apologized, retroactively withdrew from the Beijing race and forfeited the ranking points she had earned. HYROX also acknowledged shortcomings in its handling of the situation and moved to clarify its competition rules.

What Happened to Joanna Wietrzyk at HYROX Beijing?
Wietrzyk was competing in the Women’s Pro division at HYROX Beijing on Saturday, September 12.
HYROX combines endurance running with functional fitness. Athletes complete eight one-kilometre runs, with each run followed by a workout station. The exercises include SkiErg, sled pushes, sled pulls, burpee broad jumps, rowing, farmers carries, sandbag lunges and wall balls.
Unlike a conventional road race, much of HYROX takes place inside an enclosed venue, with athletes moving through common workout areas and using equipment that other competitors subsequently encounter.
During the Beijing race, Wietrzyk experienced sudden bowel incontinence but continued competing.
She eventually crossed the finish line in 1:01:23, initially recording the fastest time in the Women’s Pro field.
McElheny finished 45 seconds behind in 1:02:08, while Japan’s Aki Yoshida finished third in 1:04:52, according to published race results.
The incident subsequently attracted widespread attention after footage circulated online.
Much of the discussion centered on two separate questions: whether Wietrzyk should have stopped competing and whether race officials should have intervened because of potential hygiene and athlete-welfare concerns.
Joanna Wietrzyk Apologizes and Withdraws From HYROX Beijing
Several days after the race, Wietrzyk publicly apologized for continuing.
She explained that she had felt healthy before competing and had no reason to anticipate experiencing the problem during the race.
Reflecting on what happened, however, she acknowledged that she should have stopped competing.
“Looking back, I regret the decision to not have stepped off the track.”
Wietrzyk apologized to those affected by the incident, including fellow competitors, spectators, organizers and people in China.
She subsequently announced that she would retroactively withdraw from HYROX Beijing and forfeit the points earned from the competition.
The decision changed the competitive consequences of a performance that had initially put her at the top of the Women’s Pro results.
HYROX Says Officials Should Have Intervened
HYROX also acknowledged that the situation should have been handled differently.
Co-founder Moritz Fürste said organizers had made a mistake by failing to respond immediately during the race.
“HYROX made a mistake by not reacting immediately during the race.”
The organization subsequently reviewed how its existing medical and contamination procedures were applied during competition.
HYROX’s response was significant because the controversy was not solely about an athlete deciding whether to continue.
Race officials are also responsible for determining when a competitor’s condition could create a medical, welfare or sanitation issue for the athlete or others participating in the event.
HYROX Clarifies Rules After Beijing Incident
The Beijing incident has led to clearer provisions governing when officials can remove an athlete from competition.
Under the updated DNF provisions, a race director can medically withdraw a competitor when bodily fluids or waste—including blood, vomit, urine or feces—create a welfare or contamination risk.
An athlete withdrawn under those circumstances can be classified as DNF, or Did Not Finish.
The provision is particularly relevant to HYROX because of the competition’s format.
Athletes repeatedly move between running sections and functional workout stations inside an enclosed venue. Equipment and competition areas can therefore be encountered by many competitors throughout an event.
An incident involving potential contamination consequently has implications beyond the affected athlete.
Who Is Joanna Wietrzyk?
The viral nature of the Beijing incident introduced Wietrzyk to an audience far beyond the HYROX community, but she was already one of the sport’s leading female competitors.
Earlier in 2026, the Australian athlete set a Women’s Solo Pro world record of 56:03 at HYROX Phoenix.
The performance improved the previous world record by 20 seconds and completed Wietrzyk’s sweep of three HYROX Majors that season.
She later finished second in the Women’s Elite 15 Solo competition at the 2026 HYROX World Championships.
According to PUMA, Wietrzyk’s 2026 season included two world-record performances and a sweep of the HYROX Majors.
Her status as one of HYROX’s prominent competitors contributed to the attention surrounding what happened in Beijing.
Why Can Bowel Problems Happen During Intense Exercise?
Although the circumstances surrounding the Beijing race were unusual, gastrointestinal problems during intense endurance exercise are well documented.
Athletes can experience symptoms including abdominal discomfort, nausea, diarrhea and an urgent need to use the toilet during prolonged or high-intensity exercise.
The phenomenon is sometimes informally referred to as “runner’s trots.”
Exercise-related gastrointestinal distress can be associated with several factors, including changes in blood flow to the digestive system, dehydration, heat, mechanical movement, pre-race nutrition and exercise intensity.
Research discussed by The Guardian following the HYROX incident noted that gastrointestinal symptoms can affect a substantial proportion of endurance athletes, although the type and severity of symptoms vary considerably.
High-profile endurance athletes have experienced similar problems in the past.
British marathon runner Paula Radcliffe, for example, famously stopped during the 2005 London Marathon because of gastrointestinal distress before continuing and winning the race.
The circumstances in Beijing were different because HYROX is an indoor competition in which athletes move through shared workout areas and use common equipment.
Athlete Welfare Versus Competitive Instinct
The incident raises a broader issue about the limits of perseverance in elite competition.
High-level athletes are conditioned to continue through fatigue, discomfort and unexpected setbacks. That determination can be an important part of competitive performance.
But circumstances change when continuing to compete could affect other participants.
In an indoor competition with shared facilities and equipment, organizers must consider not only the affected athlete’s condition but also hygiene, athlete welfare and the safety of other competitors.
Both sides have now acknowledged that the situation should have been handled differently.
Wietrzyk said she should have stepped off the course. HYROX separately acknowledged that officials should have intervened.
That distinction makes the Beijing episode more than an embarrassing moment experienced by an individual athlete. It exposed a situation in which competition procedures were not applied effectively in real time.
What Changes After HYROX Beijing?
The immediate competitive outcome has already changed.
Wietrzyk has withdrawn from the event and forfeited the points associated with her original result.
For future HYROX races, officials also have clearer authority to intervene when bodily fluids or waste create a medical, welfare or contamination concern.
That may ultimately be the most consequential outcome of the Beijing incident.
For Wietrzyk, it represents an uncomfortable episode in a competitive career that has otherwise included world records and major HYROX results.
For HYROX, the incident has become a test of how a rapidly growing global fitness competition balances athletes’ instinct to continue racing with organizers’ responsibility to maintain safe conditions for everyone on the course.
