In Cheetahs, Ultimate Speed Demons, naturalist Steve Backshall runs a footrace with a cheetah. Then he reviews slow motion video footage of a cheetah running to explain how the cheetah is able to accelerate so quickly. This video is excerpted from BBC's Deadly 60, an award-winning nature and adventure show for kids in which narrator Steve Backshall has one mission: to travel the globe in search of 60 of the world's deadliest animals.
