San Diego Zoo Safari Park have started putting on daily blink-and-you'll-miss-it Cheetah Runs where the big cats show their speed by running from 0 -70mph in just four seconds.
Once a day visitors will be able to watch one of the three cheetahs there -- Amara, Johari and Shiley -- show off their impressive speed.
They will each chase their favourite toy which will be mechanically pulled along the 330-foot track in front of a visitor viewing area.
Organisers say: "If you're close enough, you may feel the wind as the cheetah passes by. The spotted sprinter races on a straight 330-foot-long track that allows the cheetah to really stretch its legs"
The event is said to take place at 5.00pm each day… and at those speeds is probably over by 5.00pm and six seconds.
