For most people, MayoClinic.com recommends a minimum of 150 minutes of moderate exercise, such as jogging, each week for basic physical fitness. Workouts should be spaced out during the week. For example, you might jog 30 minutes a day five days a week. However, you can achieve better physical fitness and greater health benefits if you increase this to about 300 minutes, or five hours, each week. If you jog five days a week, your workouts need to average 60 minutes each to reach this goal.

A person with a reasonable amount of fitness could do it in 45 to 50 minutes, if he or she is in a hurry. But you need a certain level of fitness to hurry that long at 9 to 10 minutes a klick.
