Mind if I join in as well? I'm taking an intro to master swim class. The Master swim class was a little intimidating to me. We've been swimming about 2200 yards. I'm not sure how much more I can swim in an hour. We've been timing our 100's the last few classes to see if we're improving. A few classes ago it was 1:37 and last night it was 1:30. We've also been working on lengthening our stroke. I started at 21 strokes/25 yards and now am about 18.

I just picked up the TI book from the library. I don't know how fast a 1:30 or 18 stroke per 25 yard is to decide if I should try and change my swimming style.
