A gripping video posted on YouTube of a high speed chase involving an Ostrich in hot pursuit of  two cyclists has gone viral.

The video  which is just over one minute long shows the bird running after the cyclists as they warmed up for the Cape Town Cycle Tour in South Africa on last week.

As they cycle downhill the ostrich starts chasing them, pursuing them for a good distance before slowing down and retreating.

Oleksiy Mishchenko posted the video on YouTube and wrote: “Suddenly, I spotted a white ostrich on my left, then this beast jumped on the road from the right and started chasing my friends! It was a little scary at first, but then I thought I gonna fell of my bike from laughter,”

“The ostrich didn’t have any problem to keep up at 50km/h and apparently they do 70km/h with no sweat”.

The video has been viewed over 329,000 times.
