Gazelle - we're staying in a village called Chedworth, which is a bit north of Cirencester. I'm not sure what my running plans are at the moment - I've sort of promised OH I wouldn't do too much as I think he got a bit fed up when I ran every day on our last holiday, but that was a lot closer to marathon day....I figure it won't do me too much harm if I back off a bit next week. I've signed up for 5 runs a week on Jantastic, but 2 of those could be when I'm back home the following weekend, so really only need to do 3, and I may well just stick with that. As things stand I'll probably just get them out of the way first thing in the mornings and run round the village for a few miles...but if I change my mind and am up for something more strenuous in the hills I'll let you know 
Mr Z - I think the firmer the better, but length is less of an issue (IMHO of course) 
. Mine is smooth, but I've also used a knobbly one before - can't say it made a difference, but it was only the once 
AA - nice 17 miler...and don't fall off the bike 
Red - great to see you back in the game. Hopefully a slow build up will do the trick. And don't worry - the fitness and lower HR will come back soon enough - I know this time last year when I was just starting again after an injury layoff I felt completely unfit, but it doesn't last to long 
5 miles tempo d&d earlier - meant to be 6 but my hip was playing up a bit so I backed off. Aiming for 6 miles easy pace tomorrow, but will see what it feels like. I'm not really worried about it, as it is something I get from time to time, and generally goes away after a bit so long as I don't overdo it. As people have said, better to get these niggles out of the way this time of year.
