Bangkok-based fitness coach Leroy Saunders has died after collapsing and losing consciousness during the Hyrox Bangkok 2026 competition last Thursday, his family said on Tuesday.
The 41-year-old South African was resuscitated and taken to hospital after collapsing during the event at the Queen Sirikit National Convention Center, according to a statement posted on his Instagram account.
The circumstances surrounding his death have yet to be fully understood, the statement said.
His family also asked Hyrox and the media to refrain from commenting until they and his team had a clearer understanding of what happened.
Family pays tribute to Saunders
‘What we can share without doubt is that until the last second of this moment, Leroy lived his life without regret or hesitation and impacted hundreds if not thousands to do the same throughout his journey,’ the statement said.
It added that the family understood that many people wanted closure and a better understanding of the circumstances surrounding his death.
‘We are aware everyone would like closure and a better understanding, and we are working hard to be able to offer this when the time is right,’ the statement said.
Known for work with combat athletes
Saunders owned IAOT CrossFit in Bangkok and was known for his strength and conditioning work with combat athletes.
He also founded Fight by Design, a physical training programme for Muay Thai fighters, mixed martial arts athletes and boxers.
Demanding test of endurance
Hyrox, founded in 2017 by a Swiss entrepreneur, has built a global following and also attracted occasional controversy.
The competition combines 8km of running with eight intense workout stations, placing significant demands on participants’ cardiovascular and musculoskeletal systems.
While Hyrox is not inherently dangerous for healthy and well-prepared participants, the event carries physical risks. Cardiologists have warned participants to closely monitor their heart health.
