MG3 - I'm afraid that I have no idea what your original question was. Looking at yYour schedule (and I'm aware that it's a one week sample so possibly not wholly representative). Overall the schedule looks like a reasonable jack of all road races plan but not very specific to the demands of the marathon.
- the Wednesday run could do with being longer to build endurance
- I wonder at the pace and purpose of the 400's on Tuesday
- I don't see any marathon pace runs there - in fact I don't see much of anything that's close to marathon pace if you're looking for 2:45.
Just my 2 cents and as the slowest runner who posts on this thread feel free to ignore 
I don't think that running part of a marathon as a training run is unheard of - it's just not usually someone with Mo's profile.
Wardi - nice parkrun. I suspect it was the gels every kilometre that did it for you.
HR - Sorry to hear your news. There's only one CRAB though!
Marigold - Good luck tomorrow. I know it's not flat but might you just eke out a PB?
JH1 - Get well soon!
Jools - I'm really looking forward to seeing how you get on at Bath - this could be your year!
Zattu - That's a really interesting translation of Lydiard's paces to Canova's ones. I've always wondered what the equivalent was. Had thought at one stage that 3/4 would be close to HM pace but then thought it might be a bit tough even for the elites. Some suggest that Lydiard would have had marathon runners doing VO2 type work in the last few weeks leading up to the marathon whereas Canova would focus on speeds just above and below the target marathon pace. I've read the presentation that Nobby put together that is floating around the internet but I've never seen a specific schedule that Lydiard put together for somebody training for a marathon so I can't really compare the two approaches.
The (very nasty) lurgy I picked up towards the end of January still hasn't fully gone and family stuff has also got in the way of my feeble attempts to train. I tried a hard 5 mile run today (think the frustration just got the better of me). 7:09, 7:26 and 7:50 followed by an early stop because of a sore right hip tells it's own story. Think I'll return to being sensible for a few weeks.
