Hiya!
I was sitting at my computer, musing over the fact that I couldn't find exercise classes to go to when the kids were at work and I actually had some free time and thought how much easier it would be if I could just go out for a run! However the one and only time I had purposely gone out for a run I thought my lungs and legs would explode before I'd even got to the end of my road! I wondered if there was any 'learn to run' websites then found out about c25k.
It is brill, I've actually done the programme a few times now (when I lapse

) and before I had an op this week was running for 30 mins comfortably.
Go for it! You'll be surprised, I was NOT built to run, but there I was actually running (or more accurately shuffling

)and even more amazingly enjoying myself!
