I have taken a lot of inspiration/motivation from these posts since I started so, thanks to all those who posted especially those in their sixties (when i was thinking maybe i was too old to try this at 53!) and to all those who have given me confidence that the plan works. I have been amazed at each new step up. I ran for 25 minutes today and felt great 4.02km / 25.25 mins, I bought a smart phone yesterday as mapmyrun was recommended by some posters.
Anyone thinking of trying, buy a good pair of trainers and give it a go!
