Actually, doing this on a fixed or SS is just taking cycle touring back to basics. Probably all the first generation of long distance cycle rides were done on a fixed by virtue of their being ridden on an ordinary.
LEJOG was first done on an ordinary.
Reliable variable gears don't appear until the 1900s. The Tour, due to Desgrange's romantic notions of the what the race should be , remained done on a fixed or single speed till the late 20s.
