Did the week's big swim today. The main set was 2 × 1,000 at 75% of my maximum heart rate. I wasn't about to try my borrowed heart-rate monitor in the water, but from a few weeks of experience, I know what 75% feels like (a fast pace that makes you breathe hard but doesn't kill you right away) so I felt pretty confident about being able to approximate it. I knew I shouldn't get my hopes up about my times, so I wasn't too disappointed to see 16:28 for the first one. But I was pretty excited to see 16:26 for the second one. Now that's pacing, baby.
I'm supposed to record my time per average 100, so here it is: 1:39. Hmph.
