I won't be in the vicinity of London, or even any of my bicycles, from around 23 December to 3rd January, so any dates inside of that range is not going to work for me. In actuality, most dates before then aren't going to work either, since I've got so many things which need to be done, and doing something like a night ride, the day before a 200 mile drive would probably come under the heading of a Silly Thing To Do.
(I have got off of a red-eye, and driven that far, but it took ridiculous amounts of Redbull, which is horrible, but does the job. I don't voluntarily care to try this again!)
If it doesn't happen on Friday, then it's probably going to have to wait until the New Year for me. Much earlier in the thread we did suggest January 22nd as being equidistantly spaced with this Friday and the next "real" FNRttC in February. That may be another option.
