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.
I takes about 7.23 for me to run a mile. when i was in the navy (got out 5 years ago) i had to run 1.5 miles in 15 minutes (10 min/mile). I would like to get back to that, but i can't run more than a minute or so before getting wheezy. it usually takes about 15 minutes to walk a mile if i'm going at a good pace.
