By my count, there are four non-contiguous splits comprising 2 sub-7' 2Ks in that piece! Not a total lapse of power production in my view but maybe considerable power/endurance lost immediately following hard efforts in inefficient gearings? The session obviously doesn't meet the most basic requirement of a continuous 10k but it does meet that criterion for a 9k. You should take the final K as the fastest cooldown in the history of indoor rowing.

I can't help but remark the "intervals without rest." I have no trouble believing you knock out 9x4' with the best when you don't have one arm tied behind your back. I agree with you that you have a habit-based aversion to continuous distance. I think the corrective is to do 10k continuous at 18 or 20spm next time round. Or you could go on pushing into higher rates I guess. Wouldn't hurt to break out of the psycho-illogical box by setting it as continuous row on the monitor. I commend your willingness to take on an uncomfortable task but I'm keeping the little Xmas tree on my rear view mirror for now. I earned it on the hare-brained long interval salvage op earlier in the week and you can't have it. Na-naa, na-naa, naaa-na.

We're doing 4x1000 Sunday? I better get some rest! I hope you're wrong and it's the 250-250 pyramid. I love the pyramid.
Say, this may be the moment for a bit of Pete Plan archaeology. Did you know that there is some evidence that the 4x1 preceded the 4x2 in week 2 of the original Pete Plan? And the pyramid preceded the endurance waterfall in the third week. According to sources for which I don't have citation handy at present, the pyramid and the 4x1 traded places because doing both 4x1 and 4x2 with one day in between was perceived as being way too much of a good thing. I think that's because every one tends to crack the whip over their own backs on the ranked and competed distances.
