I know- I know! I think too much !!
I really started out running (as opposed to exercising) because I got a bit bored with exercising, just "started" to run and then realised that I couldn't - and furthermore didn't even really know "how" to run. Even before that I only ever wanted to be able to easily walk 5K's. Now I can run/walk 5 ks and have signed up for a 14 K race in August - so at the moment, I am getting on with this C25K programme which will hopefully eventually lead me on to being able to run for 30 minutes and then I will start to train using run/walk for this 14K race and after that, who knows??
BUT - do I really want or need to run for 30 minutes continually?? SHOULD! (at my age) even be doing it???
Questions! Questions!
