I know, I know. Another running thread but what I'm after is specific advice/help for running 10K which I've agreed to do for charity. To elaborate, I normally run 2.5 - 3K five times a week using the same route and am utterly shocked at how much my body has grown used to the routine. Very naively assumed it would be a piece of cake to up it to 10 but tried it this afternoon and the internal dialogue went.. 2.5K Piece of pi$$ 3.0K Could do this in my sleep 3.5K 's'funny, my thighs are burning 4.0K I appear to be breathing out of my arrse Any tips from anyone who has run one? I suspect it's just a case of practice and I have until the 24th June but anything that will help would be much appreciated.
