Thanks guys! Its nice to have a forum where you can post and people reply to you!!
I think the main thing that I'm going to struggle with is keeping up my motivation at the start while I am finding it hard work - I am too easily swayed to thinking "I'll go tomorrow!" so all your advice and support will be fab!!
I am going to start my training this week and just have a gentle short jog and then build on it. So wish me luck!
Thanks again!
