Unplanned Mostly Easy

Today's hour was unplanned.  I just started rowing and paid no attention to aiming for a pace or heart rate.  Rowed with one hand for a bit while checking tv channels and then turned off tv.  Toward the end, had the urge to do a couple minutes of anaerobic effort, just enough force me to breathe fast for a bit, then slowed to a warm-down pace until the end.

The anaerobic bit was about 2 minutes of split #18.
