No, you didn't read that wrong.
French Olympic race walker (and world record holder) Yohann Diniz certainly left a mark in Rio during the 50km walk race.
Around the 15km mark of the race, with the hot Rio sun belting down on everyone, the poor bloke shat himself whilst running, with the cameras capturing everything trickling down his leg (see video above).
Then - if it couldn't get worse, Diniz then collapsed during the race and passed out. Watch the moment below.
But to his credit, he picked himself up and finished the race, coming 8th overall. Which is pretty damn impressive and deserves respect, but it's gotta make you wonder - what must the person who came 9th must be feeling like?
