This is absolutely, totally unrelated to running. Well, OK, the buffalo run away from the lions then the lions run away from the croc then the lions run away from the buffalo -- and I would run away from any of them.
This is an incredible video of South African wildlife, shot in Kruger National Park.
Everybody knows that lions and crocodiles are dangerous, but cape buffalo are bad animals. They have a reputation of simply being ill-tempered. They don't see well so when you get near them, you see them raising their noses into the air to smell you. Stories abound about wounded buffalo tracking down the hunter.
Run well, y'all, and watch out for wild animals,
