I learned to swim at age 38. I didn’t know open water swimming, whether in a triathlon or for the joy of it, could be simultaneously exhilarating and soothing! In Cabo Rojo, Puerto Rico, I used to run 2 miles to the beach, swim for an hour, and return home running. The last time I swam in Puerto Rico, I was startled when I saw a dolphin swimming next to me! (That was the first and only time I saw a dolphin in Puerto Rico.)
