Admittedly I walked Canwick Hill out of Lincoln. My Flatlands strategy is always no sleep so in a way I actually enjoyed a few minutes of walking.
I'm going with a bigger gear (78") this year just because I feel ready for it.
I'm in, and will be riding fixed wheel on my usual 70".
Not sure about sleep strategy this year, but I'm intrigued by this no-sleep approach Tippers. I'm currently thinking not to try to bivvy but just to nap and save the weight. I haven't done a genuine no-sleep 600 before, but my 'audax hotel' sleep last time was so poor on reflection I think I would have been better off without it.
Having done the ride once and feeling a bit of a state on the second day, I'm interested to know good strategies from those with more experience. My thinking is to knock out most of the first 400 with reasonable stops but minimizing faff at controls, prepare for dark night of the soul around Lincoln, catnap in Sleaford.
