Keeping warm while waymarking or stopped waiting for the back to regroup is one of the hardest things about the FNRttC, I find. You never know whether you're going to be there for one minute or ten, and the only thing that is certain is that if you decide to add a layer of clothing, inspect a hedge or attend to a non-urgent bike niggle, the call of "all up" will come within seconds.
The strategy I recommend if you find it a problem is to ride towards the back of the group, dressed for a lower speed and keeping moving for longer. TECing isn't a bad idea, as it's easier to judge when to add clothing if you're dealing with the mechanical (even if your skills are limited to moral support and torch-holding) that's holding the group up. OTOH, I find that trundling along with a struggling rider can exacerbate my knee issues, especially on the hillier routes like last night's. It's all about finding a balance, and only experience will tell you what that is.
Random moments from last night:
A hundred well lit cyclists in tight formation leaving Hyde Park Corner.
That comedy drunk in Balham saluting us with an air guitar performance, and advising that we watch out for lorries. You really can't make these things up...
A new record of three dead badgers.
Finally getting a clear-ish run of Reigate Hill. I think it's pretty conclusive that the speed camera isn't switched on.
The call of "Can someone please flush the loo!" to temporarily silence the scout hut's excessively noisy plumbing while fettling TC's bike.
That point where the sun was low above the horizon to our left, with the moon in an equivalent position to our right.
Sneaking off to a likely looking field and being told by the previous user that "it's basically the world's most beautiful toilet".
The view from the Beacon - that never gets old, though sometimes there's more of a view than others.
Topping up my sunburn from earlier in the week on Brighton sea front, surrounded by an air of accomplishment and bacon sandwiches, with the promised rain notable by its absence.
Cramming a frankly silly number of bikes into the Weatherspoons, with official endorsement.
Having a taxi pull alongside on the way back across Hyde Park Corner this morning, and getting "Wow, that thing really shifts!" (it doesn't - at least not under those circumstances) rather than the usual abuse.
Excellent bikes-on-trains karma throughout.
