Earlier this year we covered a project by National Geographic to record a cheetah running at full speed using high speed cameras. By strapping three Canon 1D X DSLRs and a Phantom high-speed camera to a rig, they filmed multiple runs of cheetahs sprinting. That footage has finally been released, and it's everything we've hoped for.
The cheetahs were having such a good time of it, that one of them broke a world record — the fastest 100m run run by anything on the planet. Clocked at 61mph, the Cincinatti Zoo's Sarah ran 100m in just 5.95 seconds.
And, if you stay for most of the video, you'll see that yes, they do catch the grey fuzzy thing in the end.
