DD - thanks for your answers, that makes good sense. In the balance between casual & 'advanced' running, I guess I am somewhere in the middle, but it's nice to imagine I can follow a more stretching schedule.
Minni - I also wondered why the rest & recovery days changed so much in the next few weeks...I'm used to doing the same type runs on the same days. I suspect I'll be changing the days around anyway to fit in with work.
Had to do my general aerobic 10m this morning, as I'll not be able to do it on Thu or Friday...so managed to knock it out this morning (yet more wind & rain) at 9.17m/m. Felt fine.
AA - do take it easy, there's nothing worse than pushing too hard after a break and making yourself worse.
