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.
RE: new runner - how long should it take me to run 5k? (1) For a new runner, I think a good goal would be to average under 7 minutes per mile for a 5k. 6:59 pace x 3.1 miles = 21:39. (2) After that I'd imagine 20:00 is a nice barrier. To run 19:59 you'd need to average 6:26's. (3) 18:59 - now you're starting to get a little more serious.
