When you’re running through the iMfolozi Game Reserve in central KwaZulu-Natal, there’s a chance you could happen across one of the Big Five.

I guess that’s what makes this prank from the organisers of the iMfolozi Outrun both brilliant and sadistic, with a number of runners getting a serious skrik.

The iMfolozi Outrun is a two-day trail run, with 19 kilometres on day one and 15 kilometres on day two, so maybe the adrenaline shot that came with thinking you’ve come face to face with a lion put a little extra pep in the runner’s step.

We first saw this on Good Things Guy, and you should know that there is some choice language in the video below:

I’d be swearing like a sailor if that was me.
