The ostrich is the fastest bird on land, as well as the fastest running animal on two legs. [51] [52] The highest reliably measured running speed for ostriches is 61 km/h (38 mph), obtained by speedometer reading when a car was chasing an ostrich in a straight line chase to force it to move as fast as it could.

Limitations of animal running speed provides an overview of how various factors determine the maximum running speed. Some terrestrial animals are built for achieving extremely high speeds, such as the cheetah , pronghorn , race horse and greyhound , while humans can train to achieve high sprint speeds.
A sled pulled by three to six reindeer will move at about 40 miles per hour, though it will take some time for the animals to reach their full speed. Though unable to run at full speed for long ...
Cheetahs can overtake a running antelope with a 140 m (150 yd) head start. Both animals were clocked at 80 km/h (50 mph) by speedometer reading while running alongside a vehicle at full speed. [104] Cheetahs can easily capture gazelles galloping at full speed (70–80 km/h (43–50 mph)). [107] The physiological reasons for speed in cheetahs are:
The mite has been recorded at a speed of 322 body lengths per second (0.225 m/s (0.50 mph)). [3] This is far in excess of the previous record holder, the Australian tiger beetle Rivacindela hudsoni, the fastest insect in the world relative to body size, which has been recorded at 1.86 m/s (4.2 mph) or 171 body lengths per second.

The pronghorn is the fastest land mammal in the Western Hemisphere, being built for maximum predator evasion through running. The top speed is dependent upon the length of time over which it is measured. It can run 56 km/h (35 mph) for 6.5 km (4 mi), 68 km/h (42 mph) for 1.5 km (1 mi), and 88.5 km/h (55 mph) for 800 m (0.5 mi).
In some shorts, the Road Runner makes a noise while sticking his tongue out at Wile E. Coyote, which resembles its actual call. The cartoons rely on a misconception that a roadrunner is much faster than a coyote. In fact, a coyote's fastest sprinting speed is 64 km/h (40 mph), [26] which is twice that of a roadrunner's at 32 km/h (20 mph). [10]
