I am a 46 year old female and did a mile today on a treadmill in 6 minutes.
Its about 6:15
The average For a 12 year old boy is 5:45. But, if you can run under that time, that is very good. I ran a 5:14 mile when i was 12.
6 mins or less for 1 mile.
An average time for running a mile for any ten-twelve year olds is around 7-9 minutes.
Well I am a 11 year old and I am running a 7:31
8 minutes flat.
