For all of you who like me discovered running late in life, and might feel apprehensive about starting, and continuing, I just found on the internet a very inspirational writer: John Bingham, and his penguin chronicles.
John started running in his 40s, after a lifetime of unhealthy choices and lifestyle, just like I did, and I suspect many others did too...He writes eloquently about the challenges, as well as the rewards that running gave him and has been instrumental in making running accessible to people who are not natural athletes.
If you need some inspiration to carry on your journey into C25K and beyond - look him up. His website is thepenguinchronicles.com
Hope this helps and inspires someone else, as much as it did for me.
