Australian HYROX athlete Joanna Wietrzyk reportedly soils herself during race and keeps going: Who is she and how hard is the fitness competition?

Australian HYROX athlete and fitness coach Joanna Wietrzyk is at the centre of an online debate after an extraordinary incident during the HYROX Beijing race on September 12, 2026. Wietrzyk, who was competing in the Women’s Pro division, reportedly experienced bowel incontinence during the demanding fitness competition. Rather than stopping, she continued racing and eventually completed the event in 1:01:23.

The incident quickly attracted attention after photos and videos circulated on social media, appearing to show Wietrzyk continuing through parts of the course, including burpee broad jumps. Reports also suggested that the incident affected sections of the course and equipment used by athletes who competed after her.

The reaction was divided. Some viewers praised Wietrzyk for her determination to finish despite what happened, while others questioned whether the race should have continued because HYROX is a shared competition environment.


HYROX China said the affected area and running lanes were quickly cordoned off and isolated. Organisers also said the area was thoroughly disinfected, relevant equipment was removed and replaced, and the entire carpet would be replaced and deep-cleaned after the competition.


Wietrzyk is no ordinary competitor. She is an elite HYROX athlete and strength and conditioning coach who has previously competed in CrossFit, functional bodybuilding and athletics. In 2026, she competed at major events including Phoenix, Warsaw and the World Championships. She won the Warsaw Major and reportedly set a world record in the Women’s Solo Pro category with a time of 54:25.

But the incident also raises another question: just how hard is HYROX?

What makes HYROX so difficult?

HYROX is an indoor fitness race that combines 8 kilometres of running with eight functional workout stations. Unlike a traditional running race, competitors repeatedly switch between running and exercises while becoming progressively more fatigued.

The format includes a 1 km run followed by a workout station, repeated eight times. The stations include the SkiErg, sled push, sled pull, burpee broad jumps, rowing, farmers carry, sandbag lunges and wall balls.

That combination is what makes HYROX deceptively difficult.

A strong runner cannot simply rely on cardio fitness, because the loaded exercises demand considerable muscular endurance. Likewise, someone who is extremely strong may struggle to maintain their running pace after repeatedly pushing sleds, performing lunges and completing other demanding stations.

The average competitor takes around 90 minutes to complete the race, although the event has no strict time limit. Beginners can also choose different formats, including individual, doubles and four-person relay competition.

In a doubles race, both competitors complete all 8 km of running but share the workout stations. In a relay, each athlete completes two sections consisting of a 1 km run and one workout station.

HYROX is therefore different from both a marathon and a traditional CrossFit competition. A marathon demands 42.2 km of continuous running, while HYROX combines a shorter running distance with intense strength work. CrossFit competitions can involve technically demanding Olympic lifts and gymnastics, whereas HYROX relies on relatively simple, standardised movements.

For someone considering their first HYROX, preparation matters.

A practical baseline is being able to run 5 km continuously in around 30 minutes, perform repeated bodyweight squats and complete about 10 push-ups. Familiarity with the SkiErg, rower and sled can also help. Beginners meeting that baseline may need roughly 12 to 16 weeks of specific preparation.

Perhaps the biggest mistake is starting too quickly. HYROX rewards pacing because the final stations are performed after substantial fatigue has already built up. Training should therefore include not only running and strength work but also “compromised running” — running immediately after demanding exercises such as sled pushes or lunges.

And that may be the best way to understand why an event like HYROX can push even elite athletes to their limits: the challenge isn't any single exercise.

It is what happens when you have to keep running after you've already pushed your body through seven exhausting stations.
