A mile? For real?

Today I was planning to play volleyball but it got cancelled. After running at an easy pace for about 4 miles I decided to run the stretch back to my house at a good clip. I had no clue what the distance was, but I did clock it with my cell phone. My time was 6:15. When I got home I checked Google maps, and against all probability the distance is about 3 yards short of a mile. This is in a country based on the metric system where absolutely no measurement is an exact anything! Not even the steps are uniform heights. I also found out that the loop in the only park in town is about 2 yards short of a mile. It's uncanny! So now I have two places to test my mile times.
