I will start out by saying that I found the app for C25K first, then found this site. The app is still on my phone. But two months have gone by and I have not even looked at it. I honestly think I am afraid to even try it because I know I will fail. I know that is not the right mind set, but this is coming from a life-long fat kid who has grown into a fat adult. You experience a lot of this kind of thinking.
I was very active as a kid, still overweight for my age, but I did softball, volleyball, golf, swimming, you name it, but but I was never good at running. At all. Ever.
