How many laps around the perimeter of the field would equal 1 mile

Assuming that you are referring to a football field, then 4 laps around it would be considered 1600 meters, which is 9.3 meters short of a mile. Depending on how fast you are running, I would say that it would take at least 2 or 3 seconds to make up that 9.3 to make it a full mile. I hope that this helps in some way or form!
