The Hyrox fitness racing sport is facing growing criticism and accusations of a "toxic" and "ego-driven" culture after an athlete was allowed to continue and win a competition in Beijing despite experiencing bowel incontinence. Video footage of the incident, which went viral on social media, showed Australian competitor Joanna Wietrzyk, 22, continuing to use shared equipment with visible fecal matter on her person.

The incident has led critics to brand the sport, founded in Germany less than a decade ago, as promoting a "win at any cost" mentality. Online commentary expressed outrage, with one user stating on the Hyrox World Instagram page, "She’s a woman obsessed with a title and the physical ability to get that title, no matter what." Another critic called the event the sport's "lowest level" of dignity, while a third warned, "We are all adults, that is a biohazard, and her ego put everyone there at risk."

Ms. Wietrzyk, from Melbourne, was reportedly hospitalized after the race. She later posted on social media from her hospital bed, "Go hard or go home they say... a win is a win."

In response to the escalating backlash, Hyrox co-founder Moritz Fürste issued an apology, acknowledging the event's mistake in not intervening immediately. "Hyrox made a mistake by not reacting immediately during the race," Fürste stated. "In the end it is my job to foresee these potential incidents – and I did not." He also vowed to implement changes to the sport's rules.

Following the incident, a spokesperson for Hyrox confirmed a "major clean-up operation" was conducted at the venue, including the sanitization of carpets and equipment. The sport, which involves competitors completing eight functional workout stations and eight 1km runs, has seen rapid global growth, with over 100 events held in 2026 and up to 40,000 participants turning out for multi-day events.

While bowel and bladder incontinence can occur in outdoor endurance events like marathons, the contamination risk in indoor venues like those used for Hyrox poses a more significant public health concern, according to public health guidance. The format of Hyrox includes exercises such as the SkiErg, sled push and pull, burpee broad jumps, rowing, farmer's carry, sandbag lunges, and wall balls.
