Usain Bolt might be the fastest man alive, but an average warthog could probably take him.
A warthog can run around 30 miles per hour on an average day—no training, no audience, no special wind conditions. Housecats alsoregularly reach this speed, as do grizzly bears, rabbits, and white-tailed deer. The roadrunner can run 25 mph even though it can also fly. A certain class of butterflies, called skippers, can get up to 37.
