Assuming one considers the end zones and sidelines part of the football field, about five laps around the field would equal 1 mile. More accurately, 1 mile is equal to approximately 4.96 laps around the exact perimeter of the field.
An official National Football League field measures 300 by 160 feet. Each end zone is 30 feet long, and each sideline is 6 feet wide. This results in a total perimeter of 1,064 feet. However, if one does not consider the end zones or the sidelines to be part of the field, the perimeter is only 920 feet, and 5.74 laps around this field equals 1 mile.
