How Long Should it Take. A mile equals 1.6 kilometers or 5280 feet, and is the most basic scale against which a runner or a sprinter can compare his/her speed. The average time to run a mile is around 10 minutes. In the basic training that the army provides, recruits are required to run a mile within 9 minutes. Going by this standard, it is safe to say that 10 minutes is a good estimate of the average time, since recruits in the army are physically much stronger and agile.
According to your age will also depend on the timed run. For instance say someone is 18 maybe you would be expected to do a mile in 6 minutes. If you are say 30, might be expected to do a mile in 15 minutes(these are just guesses). When I was in the Academy in 1971 I did a mile in 6 minutes. Things have changed drastically since then. last I heard on the mile run for an 18-22yr old was a 6.5 min. mile.
