I have completed C25K twice now but don't feel that I'm improving at all. For the past 2 months I run at least 3 times a week (early mornings suit me best), I make sure I eat breakfast and have some water before I go out. I don't go too fast - in fact any slower and I'd be going backwards, but I've found that I just can't manage more than 30 mins running. The last few "runs" I only got to 23 mins before my legs totally gave out. I'm starting to think "whats the point?". I know everyone has a bad run now and again but all of mine seem to be bad lately. Surely by now it should be a breeze to run for 30 mins but I'm really struggling. Any ideas what else I can do to improve?
