I started the day with a 45 minute swim. It is the best I've felt in the pool in a long time. Approximately 1425 yards

400 warm up
300 IM drill, pull, swim
3 x 125 (25 IM and 100 free)
25 w/ 1 breath
50 w/ 1 breath lap one; 2 breaths lap two
75 w/ 1 breath lap one; 2 breaths lap two; 3 breaths lap three
100 w/ 1 breath lap one; 2 breaths lap two; 3 breaths lap three; breaths lap four
100 cool down

The breathing exercises helped me to concentrate on smoothing out my stroke.
