Thanks everybody for your posts and thoughts. Merry Christmas to you all........yet another interesting line of topic has taken off and yet again I think my previous knowledge on the subject seems woefully inadequate.
Moraghan........thanks for starting the topic on warm-ups and thanks everybody for sharing your experiences on this. I can safely say, I have never given warm-up the respect it deserved in the past. As most of my training runs were similar speeds, I never really warmed-up for these and just started with the training run.
When I have done speed work before, I would only do half a mile slow-jog warm-up, then some dynamic (not sure this is the correct word?) stretching before starting my session. I've never even contemplated doing more than this before.
Sam......thanks for your feedback. I have noticed the longer warm-ups in my upcoming training. I'm more than happy to give the longer warm-ups a try (time-permitting), starting this week. I'm very lucky in the fact I have flexi-time at work, so I can take lunch from 11:30-13:30. This gives me a 2 hour window (meetings permitting) of running, showering, eating lunch and getting back to work. I can then work later to make my hours up. This should give me the ability of doing up to 8-9 miles during one lunch break, so if I can do 2 miles of warm-up/ warm-down then I will try my best to fit it in. I agree with why you had planned it the way you had. There are many days when I dont have the ability to do extra warm-up/ warm-down, so what you had planned for me (just the 1 mile warm-up/ warm-down) is far more suitable. If I have time, then I'll do the extra. 
Thanks very much for the stretches. I'll check my email now. Thanks also for the PF specific stretching. I will definitely be incorporating all of this in to my daily routine (your description does make sense). I won't run on empty every long run. I thought I'd try it to see how I felt compared to my normal long run regime. What is the longest distance you would recommend doing this on? I felt fine after 12 miles, but think anything above 15 or 16 without fuelling would be iffy, especially if the immune system is involved.
CC2...I will certainly cut down on alcohol, but I don't think I have the ability to cut it out completely for the next 15 weeks. But saying that, as I have already used up my Asics quota, the money could certainly come in handy! I am also planning on mixing up the yoga/ pilates workouts, but mainly focusing on pilates as it's my core that needs the most work.
Hilly.....it seems like I am almost in the same place you were when you first started running - attempting to run everything at 8m/m pace. anything more than that I would see it as a failure and be depressed about it. Thanks to Sam and comments like yours, I'm starting to see a totally different view on this. I still doubt I'd be able to run before work in the mornings though. But running in my lunch break and then again in the evenings is definitely a possibility. Thanks for the link to the HADD approach. I haven't had time to read it all yet, but will print off for the train ride to visit family just after Xmas......it'll make good reading material!
Barry.......I do think 2 marathons a year is the optimal number, and like you I think from now on I'll concentrate on a Spring marathon and then an Autumn marathon. Good luck for Berlin? Have you done it before? It's one of my favourite races and I also love the city as well.
