Finally! I started with the University Masters Swim club last night. Due to the construction at the University pool the start date for the club kept getting pushed back. More good news, my heart rate has been slowly returning to normal. It is still pounding away but not nearly as fast. With the amount of cardio I have been doing it still surprises me.
My first experience with Masters swimming was a little rocky. I messed up on the start time and showed up half an hour late. Then while swimming I developed this painful pinch in my shoulder. I also kept running into everyone. I guess I'm not used to swimming with that many people per lane.
Other than that I felt pretty comfortable with the drills and the distances.

8x25m free
50m choice
8x25m kicking (alternating kicks)
100m free
4x75m arms (using pullbouy)
6x50 free
100m back

I'm not sure what they did for the first half hour but it was a pretty laid back first session.
Afterward I lingered in the pool for a few more laps so I could get some 1on1 training with my backstroke. I plan on utilizing every minute of coaching I can get.
