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.
The time it takes for a horse to run a mile depends on it's speed, level of training and fitness and how much weight it is carrying. A Thoroughbred can run a mile in roughly 2 â¦ minutes, while it usually takes other breeds 3 or more minutes.aited horses-- who do not trot-- can do a 'running walk' as fast as 15 mph.
