With no sleep debt in advance you can get by on surprisingly little.
Not quite the same distances (but not too shabby):-
London-Edinburgh-London in 2009 I had ~10 hours sleep during the 5 days (115h was my elapsed time, 70 hours riding time for the 1426km). I finished at ~3am or so and didn't go to sleep until 10pm that night. 45 hours off the bike is a lot of faffing, especially for only 10h sleep.
Paris-Brest-Paris in 2011 I had ~10 hours sleep during the 4 days (87h53m was my elapsed time, 55h riding time I think for the 1228km). Started the ride at 8pm so I'd been up since 7am on the first day. Finished at midday-ish and got a few hours sleep that night (on the floor in CDG airport). Flight at 7am, lift home from Heathrow from a friend, shower and then an hour long nap in the bath (joy) and then out the door to get myself to the Isle of Wight by train and ferry. I was up until ~2am when I got there but slept very well that night.
Managed to do much less faffing on PBP, only 22h dedicated to resting, eating, pissing, etc. (I even had a shower after the first 1160km).
