Ancient Rome and Jogging

It has come to my attention that my associate has failed to mention Ancient Rome in his recent discussion on jogging.

As we all know, Ancient Romans had knives, but they didn't have the number '0'. In my many minutes of research, I have also failed to find any reference to Ancient Romans jogging...marching, sure...but not jogging. It thus follows that jogging depends on a civilization having discovered the number '0'.

Had the Ancient Romans discovered '0', they would have had discovered jogging as well, and everyone would still be speaking Latin today.
