Sorry to hear you've had to bail out, Goldeagle- I'm still hoping for a late burst of enthusiasm- managed 2x11 milers to/from work in the space of 12 hours- run home, eat, sleep, wakeup, run to work. If I can do this at least once per week, possibly building up to twice, then I'll be fine..............the odd much longer run needs to be thrown in for good measure, but I think the medium long ones are very useful.
