Yea, good distance rowing at 10 MPS (i.e., with maximal efficiency) is largely a matter of slide control, getting used to using sequencing, timing, posture, rhythmicity, and the efficient use of the entire body tto carry your stroke; then adding in slide with your legs as you need power to maintain the ratio as the rate rises.
If you get the hang of this, you can reduce the peak power with your legs that is necessary in order to maintain the ratio given the pace/rate.
For instance, at 1:43 @ 29 spm (11 SPI, 10MPS), I only need 100 kgs. of peak power with my legs.
That isn't much, really.
Even for a lightweight, this isn't rowing well at full slide at all, but rowing with 80% of full power overall (11 SPI, not 13 SPI), so at about 3/4 slide.
The best way to learn to row efficiently over long distances, I think, is to stay comfortable but rate 28-30 spm, with 29 spm as a center.
If you row well, to do this, you have to lighten up your stroke considerably, and as time goes on, this lightening up, just to stay comfortable, settles into 10 MPS.
At 29 spm and 10MPS, you go along at 1:43.
That's what I am doing now.
I think I'm going to row a HM, 1:43 @ 29 spm (11 SPI, 10 MPS).
Given how well I row now and my physical condition due to my extensive cross-training, this is _very_ comfortable rowing, well under my anaerobic threshold.
I just have to relax more and more with it until my heart settles down entirely into steady state at my anaerobic threshold.
When that happens, I'll be able to do it for 75 minutes.
I have no problem rowing at my anaerobic threshold for 75 minutes.
In terms of pace, the major question for me has not been whether I can row at my anaerobic threshold for 75 minutes, but how effective and efficient my rowing can be when I am doing this.
I am now _much_ more effective and efficient than I was in 2003.
How much?
6 seconds per 500m in a HM, 3 seconds per 500m in a 2K.
1:43 for 60min is right around 17.5K, half a mile (800 meters) more than I pulled back in 2003, when I did 16.7K for 60min (1:48).
1:43 for 60min predicts a 6:12 2K.
60min is done at 2K + 10.
Historically, no 60s lwt has ever pull 16K for 60min.
The 60s lwt WR for 60min is Greg Hodge's 15928m.
For a 60s lwt, the challenge of all of this, I think, is not aerobic at all, but skeletal-muscular and technical--how to generate 11 SPI, easily and anturally, at 3/4 slide.
Most 60s lwts row a 2K (which is usually done at 90% slide) at about 9 SPI.
That is, about 3 SPI short.
3 SPI at 30 spm is right around the difference between 16K for 60min (1:52) and 17.5K for 60min (1:43).
90 watts, 9 seconds per 500m.
