How fast can roaches run?

Answer 1

The fastest recorded speed measured for the American cockroach is nearly 2.0 miles per hour, or nearly 75 centimeters per second! In the absolute sense, this is a much slower speed than many vertebrates are able to attain. In relation to body size, however, it is remarkably fast. If speed were increased proportionally, an American cockroach the size of a lion could run about 50 miles per hour.
