If you are curious about a good conditioning program I found one recommended by Mark Allen (6X Ironman Triathlete). The biggest mistake individuals make when they start any training program is that they have to start off heavy and hard. Big mistake. You want to start off slow and gradually increase and you always want train at a higher distance than you actually plan to run...train at 3 miles to run a 1.5 mile run. Also, you do not have to achieve 80-90% of your target heart range every time you run. The big misnomer is that in order to develop the cardiovascular system you have to exercise at peak levels. Mark Allen suggests when you run, to try and maintain 50-60% of your target heart range for an extended amount of time--usually 1-2 hours. Anything over an hour is sufficient. Then to offset this routine--try one day of hard, intense exercise--running on hills or timed runs. So two or three days dedicated to smooth, long runs and a single day for explosive, intense runs or bike rides.
To get you ready for the run try this regime:
For the first month, do three miles but do a run/walk routine. Meaning you run for 2 minutes and walk for 3 minutes. Keep alternating the entire three miles. You may think that this is easy, mostly because it is, but you are conditioning your heart and your lungs. The next month you change the run/walk rotation to 3 minute runs and 2 minute walks. At the end of this month you are ready to start running for the entire time. You may think this is a waste of time, but it is an effective way to train. Once you can run 3 miles at a steady 2 minute quarter mile you will be ready to pump out a ten to eleven minute 1.5 mile run. How? You will have developed a natural pace that you are able to recognize and maintain. Like anything you will do in life--if you do it right the first time it will carry you on throughout. Once you have accomplished your 3 mile goal move on to 6 miles, or whatever your pace dictates. Sprints before or after your runs are also effective--or on your off days. Set your routine to meet your needs. You can adjust this run routine as well to two week increments--meaning you do 2/3 run/walk for two weeks and vice versa the next two weeks.
Along with your running regime you should go to the gym and do a full compliment of leg exercises and stretches--not in the same day and usually one-two days a week will suffice. You do not want to concentrate on heavy weight as much as high repetitions. You are trying to develop stamina and endurance, not bulky legs. Keep away from squats--they will ruin your knees and can contribute to long term injuries. Stretching is important as well--stretch everyday and when you do it, do it deliberately not any of this five second dynamic stretches where you bounce up and down. Grab it and hold it for up to thirty seconds.
When I started running I had a thirteen thirty run time. Within three months I was able to move up to 10:10 run time and I am getting faster every week. But I do not concentrate solely on my 1.5 mile run time. I am now doing 6 mile runs--my fastest time has been 50:06. This is effective because I have developed a good pace and I am able to maintain it--mostly...I am about 2 minutes off a 2:00 minute quarter mile pace for the entire 6 miles. But you have to take the initial condition time to get to this level...it doesn't just come because you will it to happen. Even if you run till you puke and just barely get the time--you will not be able to maintain in OCS and beyond. Start good habits now and they will carry you throughout.
