Hi, after lurking a lot I thought I would introduce myself. I so enjoy reading everyone's posts, and it's encouraged me to continue. I am 55, and I cannot believe I am doing the C25k. A couple of months ago I'd gone to the GP with knee pain, I did some exercises and I lost a bit of weight. My son was doing C25K, and encouraged me to have a go.Today I did Wk5R1. It was hard, but I did it! I have expected to give up, or redo weeks, but I've found it builds up slowly, in a manageable way. If I can do it, anyone can. Thanks for the encouraging posts.
