The Tire God is disturbed

My lack of respect for the Force has disturbed a greater entity.
I punctured yesterday morning, actually ruptured is a better description.
Swerved a monster pot-hole in the dark, caught a large piece of flint on its perifery and sliced the wall of my near new 26mm Conti 4 seasons clincher and tube. Both a right off.
My heresy in engaging with the shadows lurking on the dark side of 100 psi has been duly punished by the Force.
My hand pump is good for 60 - 70 psi and once I was on my way the difference was blatantly obvious. I'm sorry but a 200 lb total weight on 60 to 70 psi is just not happening for me. OK maybe for a 140 lb rider it works (when I was a 140 lb rider it still didn't but hey, that was then) but yesterday it was not even close.
As you go up thru 20 mph the extra load on your cranks is blindingly obvious. Perhaps when you pass beyond 25 mph you go thru an event horizon and the flat spot where rubber hits the road decreases and roundness and speed propel you onwards and upwards to a better place, but I have my doubts.
This morning I used my track pump and put 105 psi in both and flew down the road.
