After a health check just before Christmas ( good timing by the way...) I had a shock when I was told quite sternly to loose weight and to reduce my relatively high cholesterol . Loosing weight was tough but starting the excercise was scary. I kept on putting the moment off until my son introduced the c25k app to me and urged me to try it. It’s been 4 weeks since I started and I am , amazing , myself by quite enjoying it. It’s not fast and I get bright red by the end but I am determined to get to the point when I can run for more than 5 minutes without keeling over. I have a date with my son to run the local Park Run which I really want to keep....however all my running so far has been on the treadmill . The question I need some advice about is - when I eventually tear myself off the mechanical road is how hard will it be?Please can you let me know?
