if we hold a short-distance race for all animals, the cheetah definitely wins the gold medal!
With a top speed of 70 miles per hour, cheetahs deserve to be crowned with title "the world's fastest short-distance runners." If we hold a marathon,however,animals such as gazelles or horses can defeat cheetahs easily. Why is what? Well, while cheetahs are running, their body temperatures rise quickly. About 20 seconds after the race starts, cheetahs become too overheated to continue the race,and they must stop.
