Any question answered...

Yep. But I had already completely disassembled the bike and put it in bin bags. Spending today putting it all back together. On the positive side, I've finally cleaned everything.

£30 is good if you're willing to pay it and set it up in advance. Next time I will buy a proper cycle bag. And not try to do it on a fixed that really isn't set up for that kind of riding. :^

I did London/Paris fixed this easter too. And took the eurostar back. What route did you take?
