Presuming you were on a slightly bigger tyre setup?
I kind of prefer solo DIYs a lot of the time
I actually put smaller tyres on, not for good reasons, just I needed to swap wheels and that was what I had, so I was on 25mm Schwalbe Ones, so basically no grip on slippery off-road sections!
Psychologically, it was interesting. My first all day ride for a year, and I really got into it once I'd done about 200km. Had a wobble around 140 when lots of things were hurting and the sunk cost wasn't too great. At about 300km I was only about 30km from home so recognised beforehand that was a danger point, but there was no way I was quitting then. And I wasn't looking forward to it getting dark when I was still on the lanes. But I really enjoyed it, much more looking back than at the time, of course!
I love tubeless. On the second last big climb in the dark lanes, I had just realised that I was in danger of running out of battery power for lights and GPS (it was ok), then I heard the rush of air from a puncture. I just said to myself, 'fuck that - no way am I getting off to sort that out - I'll let it seal at whatever pressure it wants to and just ride on it, 20psi or whatever'. It would have been really horrible to have to get off then and have to change a tube.
