Also if you don't have a heart rate monitor, try keeping yourself at a pace where you're just starting to breathe harder and sweat and still able to talk if you had to. This is roughly where your target heart range is. If it's hard to talk...you're pushing too hard.
Try doing a mile for a week, the following week try adding a mile or half if you can't do that. Continue to do that, also keep in mind try to take recovery days if you felt you really pushed yourself one day. You don't want to over train, it will really screw you over. What will happen is you'll just start going downhill if you do. Things will get harder and harder and you'll end up plateauing, getting bored, and stop running. That's kind of what happened to me in high school my senior year.
