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.
From this you can see that the average male takes about 2 hours to complete a half marathon and the average women takes about 2.5 hours.The average man is therefore running each mile in 9.5 minutes and the average women in just over 12 minutes.
