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.
Getting Started. 1. Figure out your current speed.(Make sure you stretch before you start to run.) Before you can increase your speed, it is important to time how fast you are currently running, so you can accurately measure your progress. Use a stopwatch to time how long it takes you to run a mile. Once you have an exact time - whether it's 8 minutes or 16 minutes - you can work on improving it! This is where running on a track comes in handy, as each 400M lap of the track is equal to 1/4 of a mile, so four laps of the track is equal to one mile.
