1250 Yard Swim

Swam for 25 minutes, practicing swimming with head down, which I thought I did, but discovered I did not. Hard to do, swimming staring straight down. Then I tried some breathing from the left side only and I about drowned after 25 years. I did better at bilateral breathing, but can't keep it up for more than 50-100 yards.

Overall I did not swim too well tonight, and for the first time felt some back stiffness while swimming.
