While running is great, not all running is equal for weight loss. Probably the best thing to do is mix up the runs. There are some great fitness bands that, when combined with a smart phone, may help you with your goals.
1. If you have hills near you, running hills in general increases weight loss by about 10%. Also, USMA has hills (Stony Lonesome). So get use to them.
2. LSD's. Long, Slow, Distance. At first don't worry how far you are going, but worry more about how long you run. Try and get to being able to run 2 hours. If you get to the point where you can run 90 minutes you increase the ability of your body to burn fat.
3. Intervals. These will help your 2 mile run time which is not a long distance run. Do 220s, 440s and 880s. The goal is to increase your VO2 max.
4. Fartleks. Fartlek is Swedish for "This sucks". Actually it means speed play and it is a "fast/slow" interval run. I use a timer on my smart phone. I set it for 15 seconds on, 45 off. You can use visual markers as well. You want to sprint for about 50 meters (or 15 seconds in my case), then recover with a jog, or in my case I jog for 45 seconds. Do this for about 45 minutes. This will also help with your 2 mile run.
Burpee w/ pushup. They suck. But one of the most effective exercises for weight loss. You can mix them in with intervals for a great work out. Run a 220/440, rest for a minute, do 10-15 burpees. Rest a minute. Repeat.
