I graduated the C25K programme towards the end of Aug, and have continued running 5K two to three times a week. I'm very slowly getting faster (though don't think I'll achieve a sub 30 min 5K anytime soon), am feeling fitter (getting to the end of each run no longer seems like small miracle, though I'm always pleased), and, as a bonus, when I tried on some work trousers that haven't fit me since having my eldest 5 years ago, they fit! I must have slimmed down a bit too...yay!
Just so pleased I started C25K...what a great programme!
