It's two small (technically front) Carradice panniers for me, on the back. (And mudguards.)
I'm all packed up now, bar the stuff I'll wear on Friday and the bits and pieces that will go in the bar bag. And to get more €€ tomorrow.
The only thing I'm dithering on is waterproofs. Do I take the Gore, which are just amazing but which take up a bit of space?
Or... the teeny tiny packable stuff that is waterproof but much less breathable/comfortable, on the gamble that it will not, in fact, rain and therefore I won't need them?
Of course if it really does rain, I will wish I had the Gore set and, if I do in fact have them, I won't begrudge them the extra space they take up.
Hmmm.
ETA: tuck Gore waterproofs in a bag under the strap over my rack. D'oh. That's what I did in Scotland, worked a treat. How did I forget that? Problem solved.
As you were.
