Wow thanks PATTERD707. The swim is one of the things that I'm finding is a great equalizer. I'm surprised that I can swim for an hour or so and pound some speed intervals, and then climb out of the pool and not feel completely destroyed. And it's not just that I've acclimated - I was seeing that even at the outset of my adventure.
