Hi all, would like to first say what a great forum, lots of encouragement and inspiration was just what I needed to make a start and get running. As someone in there mid 40's who hasn't exercised for a long time it hasn't been easy but have surprised myself in how much I am enjoying it, without the C25K program and Laura's podcasts I might not have started at all. Did week 3 run 1 yesterday morning felt great that I got through it but it has left me with a sore knee! I'm gutted as I don't think its muscle do I run or do I rest? I don't want to have to quit now as I feel I have just started.
