Hi Pollard, nice to drag you off email. I agree with you - I think. I've not been running long but my most memorable runs have been in cool or cold weather. It's something of a cliché to say it but it's wonderful to find yourself out on a long run on a crisp, wintry, Sunday morning. Once you get through that freezing first half mile, it's just great. I remember a January run this year that was just amazing.
(In fact, I've just reread it. It's here:
Jan 5 2003 )
That said, I still find that turning that corner between Summer and Autumn a bit of a gloomy point in the calendar. I'll get over it....
