I did W1R3 today and I seriously can't believe I'll ever get to the end of this and manage 5k! I'm 54 and I hate running but love walking! I have been worried by the recent TV health programmes so thought I'd give it a go! I am really determined to be fitter by Christmas. If I can manage it, it really will be a case of almost anyone can! Found week 1 really tough but think I could just about manage week2 if I slowed down. Anyone else felt this worried at the end of week 1 and actually got to week 7? Or further?
