So what's it like in regards to staying warm or keeping cool?
I am picturing starting off freezing my bollocks off and then warming up but the night air keeping me chilled.
Or else stopping midway for the break, and getting warmed up, then being frozen again after stopping moving.
Has anyone done it at a slower pace, and not stopped at all?
I think this is what I would prefer to do. Whenever I stop my legs tend to sieze up, if I keep motoring along it works out alright in the end.

Apologies if this has been asked / discussed elsewhere before. I'm a relative newbie to Lahndan.

This is how I find it:
Usually it starts off just fine - short sleeves are okay, then about 11pm starts to get a bit chilly so on go the arm warmers. Then after the food stop (usually about 1-2am) put on every stitch of clothing I have with me and still my teeth chatter, this lasts for about 10 mins then off comes the jacket again and the rest of the trip is long sleeves/arm warmers ––––UNLESS IT'S RAINING ALL NIGHT ----- like a few years ago.

I've not done it without a break, but the time it rained all night I should have, after queueing outside in the rain for half an hour I was so cold and miserable. Last year I rode most of the route really quite slowly with an un-fit Oliver Schick (after doing in his elbow) and it was really enjoyable. Would have been better if some pubs were open later than they were though.
