The water temperature is still great and the beach is a lot more picturesque than in summer. I set a new 800 PB of 2:32. The first lap was intense, I was breathing like a drowning rat. Most of the second lap was a struggle against fatigue, and then I got some extra energy to sprint the last 150m or so, which felt great.
I have a friend (also a singer) who ran 2:20, so the ultimate goal is to beat him.
