happyrunning, you should think about doing a recce of the route in advance if you can. Last year I didn't get a chance to do one cos I was switched from leg 1 at the last minute and was very lucky not to get lost several times. I had to stop a couple of times to ask the way to Stroud...
BTW, I think I got round in about an hour and a half last year. Should be able to beat that this year now that I know the way!
