20km

And the tire stayed on. That must be a good sign. I did forget to put the valve cap back on, but had brought a spare tube and used the one from it when I realized it. I rode to the beach and back without any issues. I think I'm over sensitive now though, as every bump feels monstrous and I wince when I go over any amout of gravel...

I do have one concern -but this arose before the flat. Sometimes I get a 'floating' feeling in the back end of my bike, what is that? Is it normal? Does it mean I don't have enough air in my tire?

Anyway, success today! Yay for me!
