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.
The average person may struggle to run a mile quickly if they have not put in the appropriate training. Males can generally run faster than females, and younger people have an advantage over older people. Those who are dedicated to a training regime should be able to run the mile in under seven minutes, and elite athletes should take less than five minutes to complete one mile.
