Thursday: 3 x 25′ / 3′ rest (8′ @ 5kp, 17′ @ mp) – Breakthrough workout

I was a bit intimidated by this workout.  It wasn’t that I thought I would fail, I was pretty certain that I would complete it successfully.  Rather, I was dreading the 17 minutes at marathon pace.  In previous attempts at these step down workouts, I dug so deep in the 5kp section that the marathon pace sections were very taxing.  My HR stayed high and it was miserably hard work.

I was surprised and delighted today.  This workout didn’t feel easy, but I felt really good throughout.  My HR was way lower than any workout like this that I’ve done over the past few weeks.  I felt so good that I did the last 5 minutes at half marathon pace.

I looked through the metrics.

  • A little bit of drive length variation in the last interval
  • peak force varying with power
  • you can see the same thing in the work per stroke.  I was effectively underrating the fast stuff and over rating the slow stuff
  • I see more variation in rhythm today.  Not sure why

Comparison to the 4 x 15′ (9′ @5kp, 6′ @ mp) workout form earlier this week.

  • Same powers, just different durations so it gets a bit confusing after the first rep.
  • Nearly identical stroke rates for the faster bits.  A bit lower for the slow today (because I felt fantastic)
  • The difference in HR is astounding.  My HR didn’t go nearly as high in the 5kp sections, and it recovered better in  the mp sections.

So, why was it better?

  • time of day: nope…same for both
  • nutrition state:  nope…fasted for both
  • amount of sleep: nope…~6.5 hours before both
  • temp/humity: nope…same for both
  • accumulated fatigue:  If anything I should have been worse today.  This is the 7th day in a row that I have rowed.  This session and the prior one were rowed the day after a low intensity 60 minute endurance session.

So, I am left with random variation and improved fitness.  I think there is lot of the former, and a little of the latter.

Tomorrow:  Probably nothing.  I have an early meeting, and then I head off to the airport for a trip to Korea.  I’ll be off the erg for a week.  I’m pretty bummed about that, I was just starting to see progress.
