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.
Beginning runners should start with two to four runs per week at about 20 to 30 minutes (or roughly 2 to 4 miles) per run. You may have heard of the 10 Percent Rule, but a better way to increase your mileage is to run more every second week. This will help your body adapt to your new hobby so you don't get hurt.
