I've just done the Dirty Reiver in the UK and had to drop down to the 130K from 200K as my lower back really started playing up after 100K or so. I really enjoyed the event but need something to take the stink out of the ride at the back as I've got a disc problem which stems from various car accidents when I was young, foolish and immortal.
