A triathlete vomited at the end of a gruelling men's race at the Paris Olympics on Wednesday.
Canada's Tyler Mislawchuk, 29, was seen being physically sick on live TV after finishing ninth in an epic contest.
It had come after a tough race for the men, which ended in temperatures of around 30 degrees Celsius in the French capital.
The race was won by Britain's Alex Yee, who produced a superb comeback to catch and surpass New Zealand's Hayden Wilde to take gold.
The event was postponed from Tuesday morning after organisers deemed the water quality in the Seine to not be good enough for the competition.

It was not confirmed that the races would be able to go ahead on Wednesday until the early hours, with the men pushed back to after the women's race.
That meant the conclusion of the men's race coincided with a rise in temperatures, adding to the difficulty for the competitors.
Organisers said samples taken showed 'much lower' levels of bacteria than the threshold for the event to take place, with the hope now that the future events in the river, the triathlon mixed relay and marathon swimming, will not face such uncertainty.
The 1.5km swim, 40km bike ride and 10km run proved too much for some of the field, including Mislawchuk.
Other athletes were seen sprawled out on the mat at the finish line after completing the energy-sapping course.
Conditions were also tough in the women's race as several athletes crashed in the bike section because of the slick road surface in Paris.
Guam's Manami Iijima was the first athlete to crash, with Brazil's Vittoria Lopes, Germany's Lisa Tertsch and Belgium's Jolien Vermeylen also impacted by an incident.
Home favourite Leonie Periault was also involved along with Colombia's Maria Carolina Velasquez Soto.

Lotte Miller crashed twice during the bike leg, the second incident forcing the Norwegian to pull out of the race.
Germany's Laura Lindemann saw her hopes of a podium finish heavily impacted when she fell with three laps remaining of the bike leg.
