How Many Steps Are In A Mile?

It would depend on your natural stride(the distance covered for each step you take. My stride would be 2.5 feet to 3 feet per step. So divide the number of feet in a mile by three and you would have the number of steps it takes  me to make up the distance of a mile. You could also increase the distance of your stride  if you we're running.

This can be difficult to determine. Some people walk faster than others thus, less steps will be taken. Height is also a factor. Taller people walk
faster, and shorter people walk slower. It's a simple logic really. (estimated guess- around 2,200)

I'm guessing around 1760 but it really depends on how fast you walk

2,000 walking.  1400 running

This depends on the speed of the person who is walking. Also the length of the legs also determines the number of steps in a mile as a person with long legs mostly cover a distance of mile faster than a person with short legs.
