Weedy - I wondered that, 100 calories is half a Mars Bar or thereabouts, and that just doesn't seem like much. Mind, judging by the video of this year's event there is plenty treats to stuff in your bag at the checkpoints, so maybe it's just enough to get you to checkpoint one where you can stock up on caramel shortbread?
Checkmate - yup to the taped seams - might drop them a line, I like my Ronhill, but it's not hill-top gale kind of protection. I figure that the water will get in regardless and that the seams aren't so much of an issue, more prolonging the inevitable decline of my dryness. Plus, if it's too good, then it'll stop more moisture getting out, which means I get wet from the inside instead...
Benjamin - thinking about staying over, though it's a bit more expense I don't need right at the moment - if I do then I'm up for a meal and a hello. Would be great to meet up with a runner from other shores. 
Carlisle Castle is pretty nice, and I reckon you'll like Carlisle, I've shot a few weddings over there and it's a canny place.
