I graduated some time ago and since then have been running three times a week. I decided to improve and progress to 10k by doing the bridge to 10k. It has been ok until last week. I am on week three and I just couldn't do it. I stopped and could not get going no matter how I tried. I tried again a couple of days later and failed again. I then thought I would try and do my 5k again. I stopped and felt heavy, and legs just wouldn't move no matter how many positive thoughts I tried. Is this normal ? It's lwft me quite depressed and not knowing what to so next. I feel like a fraud and can't believe I used to run!!
