Australian athlete Joanna Wietrzyk completed the HYROX Beijing competition while experiencing severe diarrhea and visible contamination, according to reports published in September 2026.
HYROX Beijing Incident and Competitor Response
The controversy began on Saturday, September 12, 2026, when Joanna Wietrzyk competed in HYROX Beijing. According to personal statements shared on social media on Thursday, September 17, 2026, Wietrzyk felt fit and healthy at the start of the race but experienced an unexpected bout of severe diarrhea that began around the Burpee Broad Jump station.
Footage of the event circulated widely online, showing the competitor continuing through subsequent stations—including walking lunges and farmer’s carries—while visibly soiled. Despite the condition, Wietrzyk finished first in the PRO Women category with a notable time. Following the public backlash, the athlete announced a retroactive withdrawal from the race, forfeiting her points and stepping back from social media to focus on recovery and personal reflection.
Rulebook Overhaul and Leadership Apology
The handling of the race drew criticism because HYROX rulebooks previously penalized minor infractions like spitting or blowing noses on the floor, but lacked explicit protocols for involuntary biological contamination.
In response to the controversy, HYROX updated its official Rulebook for the 2026/2027 season. Section 12.3 now explicitly dictates that if a racer’s blood, vomit, urine, or feces poses a welfare or contamination risk to themselves or others, a Race Director may withdraw the participant on medical grounds. Under these updated Standard Operating Procedures, such an expulsion is officially recorded on the leaderboard as Did Not Finish (DNF).
