On my last trip to Zambia, I got to walk with lions and cheetahs. Then, they showed us how they run the cheetahs. A bit of meat is tied at the end of a rope and a winch drags it round a circuit at high speed. The cat takes off after it at amazing speeds, culminating in a cloud of dirt as it comes to a sudden stop and receives its treat.
Even though I knew exactly where and when these cheetahs were going to be running past, it was still pretty difficult catching a photo of them. I like this one a lot, mainly because of the explosions of dirt flying up where the cheetah has pushed off.
