I arrived home from Denver around 1AM, so I slept in to 7:30 instead of getting up to workout.  By the end of the day, I was a nervous wreck.  Lot’s of work tension these days.  So, I decided to do a quick 30 minute session to just calm myself down a little.

The session was 5 x 6′ L4 sequences (on slides)

2′ @ 22, 2′ @ 20, 2′ @ 18 at just under 10W x stroke rate, so 170W at r18, 190W at r20 and 210W at r22.

Everything was going fine until I was starting the 4th interval, when the batteries in the PM5 died in dramatic fashion.  By dramatic fashion, I mean that entirely theatrically.  It died and came back to life at least 3 times.  Each time it totally reset the session.  Ultimately with around 8 minutes to go, it died entirely and I was rowing completely blind.  As you can see from the HR plot, I seem to need the feedback because my HR went through the roof as I pushed harder and harder while counting strokes to try to hit the rate.

I really needed this workout.  I felt much more relaxed afterwards.
