Updated on Nov. 2, 2026 in Body Building
Sydney micro influencer Jack Jones posted Halloween costume photographs to Instagram depicting Australian athlete Joanna Wietrzyk, recreating an incident in which she experienced bowel incontinence during a HYROX race in Beijing in September. The costume included a cropped black T-shirt reading 'A win is a win' and an oversized prop barbell labelled '1000 LBS' at each end.
Why it matters
The costume highlights the public reaction to a sporting incident that prompted an apology from HYROX co-founder Moritz Fürste and procedural changes to the event's rulebook. It also raises questions about how athletes' private medical moments are represented online.
The HYROX race format consists of eight 1 km runs alternated with eight workout stations. The extraction does not specify the number of athletes affected or the exact procedural changes HYROX has adopted.
