Hyrox Champion Wins Race While Dealing With Unexpected Diarrhea, Prompting Rule Change

When you hear the phrase “push through the pain,” you probably picture a gritted‑teeth sprint or a last‑rep deadlift. Joanna Wietrzyk, 24, took it a step further – she finished a Hyrox competition while literally pooping herself in front of a packed arena.

The Beijing solo women’s event on September 12 turned chaotic when, midway through the course, the Australian world‑record holder suffered a severe bout of runner’s diarrhea. By the time she crossed the line, a thin stream of waste was still trailing down her legs. Yet she still posted a time of 1:01:23 and, surprisingly, claimed first place.

After the race, Joanna posted a tongue‑in‑cheek caption on Instagram – “go hard or go home, they say…a win is a win” – only to delete it hours later as the story went viral. Spectators, fellow athletes, and even strangers on Reddit flooded the comment sections with a mix of awe, disgust and outright fury.

One Reddit user called it a “biohazard” and demanded an immediate disqualification. Another competitor, who also ran that day, argued that allowing the result to stand was unfair to those who had to use a track littered with feces‑soaked equipment. Meanwhile, some social‑media voices defended Joanna, saying that an accidental bodily function shouldn’t erase a hard‑earned victory – “sht happens,” one wrote.

Medical experts weren’t surprised by the incident. Dr. Dana Zalkin, a gastroenterologist at Mount Sinai, explained that intense exercise redirects blood away from the gut, irritating the intestines and often causing “runner’s diarrhea.” Heavy lifting, sprint intervals and whatever Joanna ate before the race likely amplified the effect.

Hyrox co‑founder Moritz Fürste later admitted the organization “made a mistake by not reacting immediately during the race.” The Beijing venue was quickly cordoned off, the affected carpeting removed, and the area disinfected. In the aftermath, Hyrox China submitted a proposal to tighten the rulebook, specifically addressing “severe physical discomfort and public‑health risks.”

One blunt suggestion floated on X (formerly Twitter) summed up the sentiment: “If you sht your pants mid‑race, you’re disqualified.” It’s a simple rule, but implementing it raises questions about athlete safety, fairness and the line between performance and public health.

For now, Joanna’s victory stands, but the incident has forced the sport’s governing bodies to confront an uncomfortable reality – literally. Whether the new guidelines will prevent another public‑health fiasco remains to be seen, but the conversation has certainly started.
