The athlete took responsibility for the disruption caused by her decision to continue competing after a bowel incident, leading to her forfeiture and the announcement of new competition rules by Hyrox.

Joanna Wietrzyk, a fitness athlete originally from Australia, announced on Thursday, September 17, 2026, that she is retroactively withdrawing from a Hyrox competition in China and forfeiting her first-place win. The decision follows an incident during the event on Saturday, September 12, 2026, in which Wietrzyk defecated while competing and continued with the race. Wietrzyk issued an apology on Instagram, stating she regretted the choice to stay on the track and took responsibility for the disruption caused to others.

The incident occurred approximately halfway through the race while Wietrzyk was performing weighted lunges. Videos from the event showed feces on her legs as she moved through the course. Wietrzyk stated she felt healthy at the start of the competition and had no reason to expect illness, but she noted the experience taught her the importance of knowing when to step away from a race.

Mo Fuerste, the co-founder of Hyrox, apologized earlier in the week, stating that competition officials did not handle the situation correctly. Hyrox, a fitness sport founded in 2017 that hosts global competitions, already maintains rules prohibiting athletes from spitting or clearing their nostrils on the floor, actions which carry a two-minute penalty. Fuerste indicated that new rules are being implemented to prevent similar occurrences in the future.

Wietrzyk’s coach described the event as an "extraordinary set of circumstances" that was difficult for judges and officials to manage in real time. The coach also condemned "hatred and personal attacks" directed at the athlete following the race. Wietrzyk, who initially posted a selfie after the win with the caption "a win is a win," stated she will now take time to reflect and recover away from public attention.

The scale of the impact involves the forfeiture of points earned by Wietrzyk during the Saturday competition, which affects her standing in the sport's global ranking system. For other competitors, the precedent set by this forfeiture and the subsequent rule changes means that future incidents involving bodily fluids—previously addressed by two-minute penalties for spitting—may now lead to more immediate or severe interventions by race staff to maintain sanitary conditions for all participants.

What happens next: The specific language and effective date of the new Hyrox rules mentioned by Fuerste have not yet been reported. Wietrzyk has stated she is taking time away from competition to recover and look after her family. Hyrox did not immediately respond to requests for further comment regarding the timeline for official policy updates or how these rules will be communicated to the broader athlete community.
