If you're thinking about PBP then just go for it. It's definitely worth doing at least once.
(I'm skipping PBP2015 as I simply don't have enough spare time for that amount of Audaxing at the moment but PBP2019 is a definite possibility and my daughter will be at a better age for a week long holiday in France whilst I'm on the bike. I'd also approach it a completely different way, aiming to do a faster ride - 75h or so - and on a geared bike maybe.)
