Already in the morning it was a beautiful April day. The temperature was already around 10C (and would hit 20C in the afternoon), it was sunny and the lake was a flat mirror.
I took out the single on a steady state row. I was out with Martin and Jiri, two other Masters rowers. We did steady state but we added a few 20 stroke bursts at race pace. Jiri and Martin are 90+ kg guys who pull 6:30 and 6:40, respectively. Still I wanted to outrow them on the single, a new boat type for them.
I noticed I was much faster in the steady state 18spm part of the row, but at race pace Jiri was close. Even though I suspect it was a bit above race pace for him, given how much he slowed down after the twentieth stroke. I happily report that of the 6 bursts I did there was one at 34spm that I really liked. A light catch, a good pull, and keep feeding the boat with more and more strokes. That’s how I like it!
I was using the RIM app to look at technique. I am quite intrigued by the “stroke efficiency” metric (http://www.rowinginmotion.com/stroke-efficiency-explained/) because I see how it correlates with rowing well when I row. At the same time I don’t really understand how it works, and I want to get my head around it.
Well, I was doing 18spm and could effortlessly get my “stroke efficiency” between 4 and 5 meters, which was about 1-2 meters more than on Friday. Did my technique improve so much? I guess the metric is quite sensitive to some subtle effects on the recovery.
What was funny though is that at one turn I fiddled with the phone, and RIM asked me to recalibrate. I pressed “OK” and RIM recalibrated. After that, my “stroke efficiency” numbers were suddenly around 2-2.5. Does the calibration influence the metric?
I don’t have the data, because RIM did to me what it already did on Friday. After 65 minutes of recording it suddenly crashes and I am looking at the iphone start screen. No data recorded. I am wondering if there is a file size limit that it hits, now that I have up to 10 gps locations per second.
Then I spent some time hanging around the club house, helping Romana with coaching and preparing for the boat christening ceremony.
We had 4 club boats and two privately owned boats to be Christened, so it was a big day. Our brand new Salani 2x was one of them. Here are the pictures:
A little explanation of our new double’s name “ORCA”.
Orka is the Dutch word for killer whale, a beautiful animal. As my single is called “Dolfijn” it is an appropriate name for a sister ship.
Orca (with a “c”) is the old spelling. Also, it is the name of AUSR ORCA, the Utrecht based rowing club where I spent very happy years rowing as a student.
