I felt far stronger after I finished and would happily have kept cycling. First few days seem hardest (particularly because they are the hardest in Devon and Cornwall) and I got stronger as it progressed. I've found this with all multi-day trips. I think the only exception would be if you were really smashing it up to your total limit, in which case you might need recovery time...
I did LEJOG in 2016 and It was my first multi day ride. I only got stronger as it went on.
I did it in 11 days taking in about 1050 miles.
You'll smash it.
In my opinion you'll only need a rest if you get an injury.
Good luck and enjoy it.
