In reply to Pete Houghton:
Whoops, I forgot, and sorry to plug away again at my inane scribblings on the matter, but I've been writing a sporadic diary of events since I started running back in April, just to try and keep track of progress and all that. I stuck it all together and neatened it up a bit, and this is the result:

It's a bit boring at first and remains that way unless you like running, but if nothing else, perhaps it might illustrate just how easy it is to get a bit fitter in a relatively short space of time: from sweating and wheezing your way through a jog-walked 10km on the flat, to finishing not-too-badly on a 50km, 4000m run.
That's it, I'll leave you alone now... (until the next adventure presents itself!!)
