We also discussed what "paces" are. Paces are a way to measure distance using parts of your body.
A pace (or double-pace or passus) was a measure of distance used in Ancient Rome. It was nominally the measure of a full stride from the position of the heel when it is raised from the ground to the point the same heel is set down again at the end of the step. Thus, a distance can be "paced off" by counting each time the same heel touches ground, or, in other words, every other step. In Rome, this unit was standardized as two gradūs or five Roman feet (about 1.48 metres or 58.1 English inches). There were 1000 passus in one mille, and a mille was sometimes referred to as a mille passuum. (Wikipedia)
Measure your pace at home using a tape measure or ruler. Everyone's pace is different and may change over your lifetime!
