The polluted Seine River, or absolute exhaustion (or perhaps both), got the best of some of the triathletes at the Paris Olympics -- especially Canadian competitor Tyler Mislawchuk -- who threw up at the finish line on LIVE TV!!!
The Paris Olympics received a bunch of criticism for the Seine River's cleanliness, with reports of high levels of E. coli and other bacteria present ... but officials believed the quality was good enough for Wednesday's triathlon, which in addition to the swim, also includes cycling and a 10km run.
The triathletes battled it out on both land and in the water .
