Thanks for all the comments.
Sarah Rowe: Thanks for the tip when walking the dog, that makes sense. In the last week i've really started to notice and feel the effects on my upper body from running, which is an unexpected bonus.
Mrs Portou 2 Be: regarding my watch I totally love it! I have the Garmin 610 and i've customised the home screen so it has 4 stats. Overall Time, Overall Distance, Current Lap Speed (I have the laps set at 1 km), and my current heart rate.
It's great for example looking at my 7k from last night and I could see that the effort was very consistent. I was around 136bpm for my first k and slowly progressed to around 152bpm by the end of the run. Because I have the 4 stats that interest me on one screen i don't have to mess around changing it at all.
The one thing that i'm not doing a lot is using the virtual runner, but I fancy doing thist this week, or next. I want to set myself a small 2 mile challenge on a rest day just to try one quick run, because I think it would do my confidence good if I can force out a short quick run, so that I know I can do it if I need to. My one and only weakness with my watch at times is when I get tired I start looking at it a bit to often counting down the distance
But when I started i was doing this every 200m, now I don't even glance at it for the first 2k except when it buzzes at the end of each K just to see my speed.
Oh the one thing I do recommend with running is not watch scary TV Programs about horrible things just before running. I watched a series of Cracker on DVD just before going running that was about rape, and had all sorts of dark thoughts in my head for the first half of the run. Completely silly I know 
Toots: your welcome, if I have any advice to anyone just starting (from my whole 7 weeks eperience) it's just this... keep going, even if it's a bad run, when you are slow, your legs ache, and you feel that it's not achieving anything, just keep plodding along, and it's all part of the learning experience. I think we all need the odd stinky run, so we can appreciate what happens when it gets hard, and we learn how to cope and just keep going.
Cheers everyone.
