I'm new here. Just completed week 2 - should have been week 3 but a lousy cold set me back. I am middle aged and unfit and do not have a particularly athletic physique (ahem!) but I am absolutely determined to do this. In week 1 I kept getting a stitch about half way through the session but that has gone now, so that's something. Everything aches but I think that's a good thing I don't think I've ever been so determined to do something as I am with this. Set myself a target - to run 10km by October next year. Do you think it's do-able?
