I think you get more responses the earlier in the morning it is - kind of a solidarity thing at being the only people up that early.
I agree with this. A run before work and several people nod or say 'hi'. A run later on and I hardly ever get a response. I always nod at the very least but I'm not too upset if I don't get anything back- at least, I've tried to be polite!
So my marathon training has been going well, I have gotten up to 20 mikes withought too much of a porblem and only had minor niggles. That was until last weekend when I ran an assault course as part of a hen weekend. I now have pain around my knee, around my inside leg and pain down the fron of my quad- this is only on one side. I ran 13 miles the day after the assault course whoch seems to have aggrevated it and I was wondering if 2 days of rest and self massage is enough as I am starting to get twitchy! I am due to race 20 miles this weekend and obviously don't want to risk not being able to do the marathon in 5 weeks time.
