That's Gotta Hurt: 100m Runner Snaps His Leg After It Bends Backwards!
We're not ashamed to admit that a giant "Arrrghhhoooooh, oh my good Christ" reverberated around the ZOO office when we first watched this.
But that's not even close to the noise we're sure came out of that sprinter's run when he heard his leg crack in two.
The unlucky man in question is Georgi Kirilov, a Bulgarian sprinter who yesterday managed to run his way to a shattered limb during the 100 metres race at the European Athletics Championships in Helsinki, Finland.
Get your wince faces at the ready and hit play to see it unfold (literally, in a way).
See? This is why we never took up running. It's massive effort AND we'd definitely snap our leg in two.
