I've got to say that "runner" is a bit of an exaggeration! I've today managed W6R3 and even shuffled along a tiny tiny bit more quickly for the last 60 seconds just like Laura suggested. I was painfully slow (OK Oldfloss I know .....) but I made it. I never thought I would. I'm now mixing my C25K with a local running club: the balancing act between the two gets a bit crazy but I'm almost afraid to admit that I think I'm starting to enjoy it.
