Poland open-water swimmer Natalia Charlos lost consciousness, was pulled to shore and revived at the European Championships on Wednesday.
Charlos “was recovering well after overexerting herself” near the end of the 10km race, the Associated Press reported.
Open-water swimming, added to the Olympics in 2008, has proven to be a dangerous sport. American Fran Crippen died during a 2010 World Cup race in Dubai, where high temperatures caused several swimmers to be treated for heat exhaustion.
Last year, British two-time World champion Keri-Anne Payne described the physicality from competitors at the World Championships 10km as “absolute carnage.”
