Over the weekend, I rode 16 miles on Saturday and 19 miles on Sunday. On Monday, I took my bicycle into the shop for a few minor repairs and a tune-up. The rear drop-out that holds the derailleur was bent. They straightened that, replaced a cable and adjusted a few things.
Yesterday I rode 13 miles and it felt so good - I felt good - in that small space of everything that works so well together.
It reminds me of how fragile a state of body, material or mind can be.
