Today's Workout--Back in the Pool

I did not swim at all last week. I did a couple of easy runs and an hour on the bike, but I slept in on the swim days. I could just feel my body needing the rest. Well, today I was back in the pool and I felt damn good. It took the entire 600 w/u to get my blood going. However, once I woke up my blood up (its on a different schedule from my brain) the work out went well. Every set we did today was a 600 of something. Since I did not keep my workout sheet today, I really don't remember everything. How sad is that?
