Is 7 minutes 1 second OK for a 13 year old boy mile run?

Well it depends. I ran a mile in 12 minutes and 20 seconds. And I don't think that I'm considered fat. It's just that running nonstop makes me tired, so I had to walk in the middle. But I can play soccer for 90 minutes and not get very tired! For some people it's the opposite.

In my PE class, the average time for mile run was about 8.5 minutes. Which, personally, I think is quite weird. My friend finished a minute and 20 seconds after me, and there's a guy who finished a few minutes after her. But most students in my class finished before me. And the average of our whole class (not only girls) is something around 8.5 minutes.
