All good stuff! It's starting to sound like S'Hampton is the place to be. I'm in Aylesbury and Milton Keynes (home and work), so a bit out of the way of SH.
How tiring is it to run in PJs? I saw the SR videos on YouTube and was watching the bockers all arriving at the finish line after running a mile looking like they were having trouble getting there - I'm not entirely sure, but I don't think I look that bad when I've finished running two miles in just my trainers.
I remember seeing something vaguely akin to bocks on, oh, I don't know, Tomorrow's World or something, about 10 or so years ago. They were being discussed as a means of allowing foot soldiers to cover a lot of ground very quickly. Nothing was heard after that for years. From what I've heard they wouldn't be entirely practical due to the weight of the bocks, and obviously wouldn't be much good over soggy ground.
Still, do they allow you to run further for the same energy expenditure or just faster?
