After progressing through the 9 weeks without too many problems I now feel that I've hit a wall. Just can't seem to get passed 30 mins (4k). Tried slowing down, changing the route, using Laura, not using Laura but I just feel I have nothing left in my legs and have to stop and walk. I really want to be able to run 5k and enter a park run with my sister but I don't want to if I have to walk part of it. Oh well will just keep on getting out there and giving it a go. I'm only running at the moment should I be doing something else to improve my fitness?
