Olympic Triathlete Who Threw Up After Race Blames Heat, Not Dirty Seine Water

An Olympic athlete’s spilling his guts on why he spilled his guts after a race … blaming weather conditions after his race in Paris’ Seine River — NOT the water itself.

Tyler Mislawchuk — the Canadian triathlete who went viral for all the wrong reasons when he hurled 10 times after racing Wednesday in the Triathlon — says he’s not used to such blazing hot weather.

ICYMI … Mislawchuk’s crossed the triathlon finish line and blew chunks within feet of his fellow competitors. Social media’s non-medical diagnosis —  the polluted Seine — but Tyler says that’s not why he retched.

Mislawchuk’s from Winnipeg in Canada … and he’s used to training in freezing cold temps — not the low 80’s.

Olympic officials pushed back the triathlon when Paris was hit with a torrent of rain … much of which flowed into the Seine and sent E. coli levels skyrocketing.

Competitors in the women’s triathlon groused about the gross conditions in the Seine … with one calling that part of the race a “lottery.” We’re assuming she means finishing first is more luck than talent.

But Mislawchuk’s not complaining about the H20 — placing the blame squarely on his shoulders after falling to six place. He’s also taking his viral puking moment in stride, posting a pic of himself with the caption, “No regrets, all in.”
