It’s not always obvious what to do when you notice the first signs of a puncture. If it’s dark and there are no light-up places to fix the tyre, what do you do? This night, I decided to inflate with the pump because the deflation was slow to start with. Then ride on as far as I could before it deflated too much. Unfortunately, next time with the little pump, deflation got faster.
Stopping to re-inflate 3 times isn’t so bad, but the time between each re-inflation was getting noticably shorter. The last interval was less than a 1km. I walked the last 4km home in all (in quite a bad mood, and hungry).

Next day, I did the repairs. The thorn that was guilty, was surprisingly long and difficult to remove. These puncture-proof tyres make pulling thorns out very tricky. If you don’t get it all out, the new inner-tube goes flat immediately. Retrospectively, the choice to walk was probably about right.
