2024 Paris Olympics: Triathlete Tyler Mislawchuck reveals that lack of acclimatization made him sick after he vomited 10 times swimming in Seine River at the Paris Olympics
The Seine River doesn't taste good, and swimmers felt debris in the water, and saw things in the water they shouldn't see. Rain in Paris during the opening ceremonies caused sewage to overflow into the Siene River. However Mislawchuk blamed high air temperature for his vomiting episode that occurred at the middle of the race. He said he is used to a cooler climate in Canada.
