coolrunning.com is a great web site. you'll find lots of information there.
and, you don't have to do the program within nine weeks--you can stretch it longer if you want.
i started out (when out of shape and overweight about 7 years ago) with daily walks. it started out with X minutes. THe first time, it was just however many minutes felt good. And i would do that for a few days and then try to add a few more minutes to it.
then, when i felt comfortable walking for 30 minutes, i'd try to increase my distance during thta 30 minutes. I had an area 'marked out' in my neighborhood (clocked the distance with my car) so i knew how far i was going. Once around is a mile. At first, once around may have taken 30 minutes. Now, i can usually get 3 around in thirty minutes.
once comfortable there, i would add running. I would start walking, and then get to a certain point (usually a particular lamp post) and then i would run to a certain point (another particular lamp post further down the road). Then, i would walk again, and then i would run another interval. I would do this for the time (30 minutes or whatever) that i'd allotted for myself.
Then, once that distance was comfortable, i would increase the running interval distances and decrease the walking interval distances.
and finally, i would simply be running.
and now, i do speed work--i run, then sprint for a distance, then run, then sprint, then run, then sprint, then run--all in a certain duration of time. And then, i walk to cool down, stretch out, and i'm good-to-go.
good luck to you!
