I did 7 with 3.5 tempo pace (6m30 for me) yesterday and then an 11M MLR today. That's a fairly typical combo in the P&D plan so I thought I'd get ahead of the curve before it starts for real next week.
Running Eye: That training sounds like what's known as "icing first" around here . It will suffice to paraphrase what everyone else has already said: you don't want to go into the marathon will all icing and no cake.
Following the Bedford Half, I took Monday off and substituted an easy run with an x-trainer session yesterday. My legs feel a lot better for it today, so will probably try some sort of MLR later on.
2015 "A" target for me is sub-3 @ VMLM. Beyond that I haven't really thought about it! Getting my weight down by half a stone or so is kind of a secondary target, I'm hoping that will mostly happen naturally once the volume racks up.
