45min @ YMCA, tempo trainer 50s - 17 strokes, from 1.45-1.27s. (1.27s@17strokes/25yd == 1m26s 100yd. which I didn't do, but still, that's so fast!!!)

pool was a bit warmer than pro club but very few people there.

edit: Possibly tweaked left shoulder/neck/spine muscles swimming too hard... Nerve pinched so badly it's been hard to sleep. More time off from the pool, I guess.
