Thanks Hank, I agree, today was not a "base" workout.  :-) I appreciate your and Mark's comments that it's not reasonable for me to expect to get up to max HR in 2 minutes (maybe max HR is possible if we were more strict on following the proscribed rest...) FYI - Here are the numbers from my pieces (I think the even-numbered pieces were down-wind) Piece, Time, avgSPM, HR avg/max 1, 2:26, 24.2, 132/151 2, 2:19, 25.1, 142/156 3, 2:16, 26.0, 143/160 4, 2:16, 26.0, 143/162 5, 2:12, 28.6, 149/166 6, 2:09, 28.3, 146/165 7, 2:16, 29.6, 151/169 8, 2:11, 29.3, 150/167 9, 2:15, 30.7, 148/167 10, 2:09, 31.8, 150/169 Of course, 70% of my starts were bad-to-atrocious...  Dale On Fri, Jul 4, 2025 at 1:19 PM Hank Koerner < hank.koerner@gmail.com > wrote: Thanks for the row and coffee, gents.  Follow-up to the morning's discussion: I think today's workout was designed to put us at lactate threshold (AT) multiple times.

Thanks for the row and coffee, gents.  Follow-up to the morning's discussion: I think today's workout was designed to put us at lactate threshold (AT) multiple times. This  helps develop the ability to handle and sustain intense efforts and build a higher threshold.  I think it worked, at least in my case.  You can see the 10 pieces* pretty clearly in the screenshot. I hit AT heart rate by the 5th piece. It went higher from there.  I conclude that I was at AT or better at stroke rate 28 and above.  As Mark pointed out, HR is a lagging indicator - it lags effort and is an imperfect measure, especially for shorter, intense intervals.  If we had rowing power meters tightly integrated with our rowing telemetry, as cyclists do, we'd see that the duration of these pieces were at our AT power threshold. But we don't and use what have -HR - instead.  As an aside, I think Garmin could do a better job capturing the physiological cost of this sort of workout and related impact on ...

+ Katherine Hey Geno, Good call today!  Ezra Klein with Oren Cass here . Here's a pic of 2 sections of Kato N scale track - 62 mm Feeder Track (20-041) and a #6 Left Turnout (186 mm, 20-202). The rails are spaced 9 mm. The Feeder Track comes with wires terminating in a standard Mini Tamiya connector Here's the underside. I have installed a Digitrax DS51K1 decoder per this link . I have also wired the turnout for non-power routing. I secure the decoder with a piece of painter's tape, which I may "upgrade" to a dab of Aileen's Tacky Glue.  The primary goal in installing these small decoders directly to the track is to have flexible track pieces that one can move and reconfigure at will without needing to disconnect wiring from beneath "benchwork" (the term used to describe traditional plywood surfaces and wood support framing). I have no benchwork; instead my layout is on an Ikea 30 x 60 desk, which can be elevated up and down.  Here's a pic of ...

Hi Steve, Thanks for reaching out. I have quite a few docs and albums I can share with you, which I'll do below. And I'll send a few pics annotated with names to faces. But I don't have time at the moment to write an "article" that might be more suitable for the newsletter. But let's start with what I have and see where that gets us. The Class of '75 Stanford Crew Reunion, Seattle, May 2025 This is the third "event" where some number of Stanford Crew alums from the mid 70's have convened in Seattle. I moved to Seattle in 1990. By 2011 I was ready to dip my toe back in the water and I've been rowing at Pocock in Seattle ever since. The rowing in Seattle is excellent. And Pocock is a good place to host alumni events.  The first of these alumni events commemorated a teammate who had died from cancer, Mark Grosenbaugh, '75. Mark, Sam Francis, '75, Dick Bailey, '76, and I, '75, spent the summer of '75 trying out for the US...

Acceleration and velocity curve visualizer This is first attempt at visualizing rowing app accelerometer and speed data. The data is from an OTW reference 1K in March. It's visualized with a Plotly for Python interactive chart. The desire is to add: basic rowing metrics including those in Rowing In Motion filters for stroke rate, bearing, etc. identification of "best" and "worst" strokes as per the metrics comparison of strokes, such as "best" strokes to "worst" or "typical"
