I have a related question -
When you nap, where's the bike?
Do you lock it? Does it mean you carry a lock for brevets longer than (YMMV) 400km?
I'm thinking of getting a flimsy lock, just for this purpose.
Something like this one:

Last week I rode 365km with friends (as practice before the brevet season that starts in less than 2 months.)
It didn't require any sleep, but we have many long stops.
In one of the stops I managed to "rest my eyes" for 15 minutes.
Anyway, in all our stops, we stopped at a gas station, and were inside (outside was too cold, below 10 degrees C,) and the bikes were left outside, unlocked.
It was ok, but in some of the stops I was a little stressful.
