I have Just completed week 6 and feel exhilarated. I am 74 and have not run for decades. A few years ago I was seriously overweight and feeling unwell with the impact of type 2 diabetes, arthritis and other oldies' curses. Over time I followed Michael Mosley with a fasting diet regime then a controlled carbs diet and got the weight under better control. Then I found c25K with the help of my inspirational daughter. I cannot believe that I have just run for 25 minutes and felt so good. Pace doesn't matter but it was at about 50% Sloth.
There have been tough days, especially when the Aussie environment has thrown heat and allergens at me. But my rule is that putting on the running shoes and getting out of the door counts as a success.
I just wish that I could help another old, overweight, unfit diabetic to give this fabulous program a real go. Oh yes, and I also wish to get to 75% Sloth speed for the full 5K.
