Turns out my ride was a little shorter, about 25 miles, therefore more like a fast 40k.
Also when I tried to put more pressure in the tire this morning, I got a pinch flat. More practice ahead.
Planning to swim in the Sycamore Pool in the morning. Friday morning is the only time I will immerse myself in said pool as it is drained and cleaned on Thursdays. Not so much floating detritus. It's good to have "open water" to swim in though. The possibility of giardia is an added thrill.
