As you may have guesses the fastest runners in the insect world are cockroaches, which can move almost one foot per second - translating to a little over 3 mph or 50 body lengths per second. This would be equivalent to a human sprinter running the 100 yard dash in 1 second or approximately 200MPH!
The fastest animal on earth, relative to body length, is the South Californian mite Paratarsotomus macropalpis, which has a speed of 322 body lengths per second. The equivalent speed for a human running as fast as this mite would be 1,300 mph (2,092 km/h).
