John, Hiya matey.
I use http://www.gmap-pedometer.com/ to record my runs. I registered there and set up the diary to input runs and distances etc. I also use http://www.myfitnesspal.com/ to record my food intake.
I have noticed my pace coming down ALOT and that again is only in 3 weeks.
My runs are getting harder if anything but by Day3 I am just about ready to move to the next week.
Problem with knees is causing my issue, but i can certainly feel the improvement in running.
Week 4 will see you increase the stamina to 5 mins probably (depending on your programme) and that for me is going to kill me, but i am sticking at it.
I have lost 7lbs in weight, eating correctly and running, I am sure you will lose the weight and increase the stamina over time but as mentioned above 3 weeks is too soon to see a big improvement.
Once we have done the 8 weeks we can run together, than I think will help us both along.
