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.
âHighâ fitness women ran the mile in nine minutes or less; âmoderateâ fitness women ran it in 10 minutes and 30 seconds or less and âlowâ fitness women needed 12 minutes or more to complete the mile. Run for Life states that a 10-minute mile rate is good for beginners; the goal is to complete 3 miles in 30 minutes. If a 10-minute mile rate seems out of reach, start with a 12-minute rate and then work downward.
