Had my second swimming workout today. Went about 800 yards (I keep forgetting to keep track). Almost all of it was 50s on the 2 minutes. Still sucking air but not as bad as last Thursday. I even went faster without trying (45 seconds instead of 50 seconds). I still seem to be the fastest person in the pool, which is so wrong, but today there were people with more endurance--flip turns, even. Give me another few months :-).
This Thursday I'm going to try a 75 or 100 without stopping. Once I reach 100, it's time to start the flip turns.
