Well, if I wanted to test how far my sprint fitness has declined, this would be a good way to do it. Also, it would be a good way to see how well my knee works for full pressure rowing.
I figured that it would be a stretch to do this session with an average pace of 1:45. To try to make myself a little less obsessive about the pace, I did the challenge with the watts screen up. 1:45 is just about 300W, but somehow, I figured I would do a better job backing off if I wasn’t looking at the pace sliding away.
I set up the session as a simple time interval session. I used the first 4 minutes as a warmup with 4 power 10s close to my target pace. Then 3 minutes of paddling. I let the flywheel stop completely before the first interval to stay legal.
The plan was to try to hold 10W per stroke, but I found that I was having trouble getting my rating up above 28, even with the power above 300W. I just went with it, but it sure felt like hard work. I finished the first interval 303 watts (1:44.6). I felt pretty toasted, but I recovered pretty well in the rest period.
I figured I should probably back off the 300w target a bit, but I set out in the second interval at 300W, but I needed to back off a bit in the second half and I ended up at 297W (1:45.6). This one really stung and I was desperately counting down the strokes to the end.
For the third interval, I targeted 280W and I hoped that would be enough slack. This one started pretty well, but I sure felt it in the last minute. I beat the 280w, but just barely with 283W (1:47.3).
The last interval was going to be very difficult. I decided to back off some more to 260W and see how it went. I really wanted to just make it through without putting the handle down. I did, 262W (1:50.0).
I did a progressive cool down, and then paddled enough meters to tick over 10km.
The summary graph shows that I was pushing this one close to the edge. My max recorded HR is 185 and I matched that the last interval.
This workout shows how using power is a better way to manage intensity for hard workouts. HR lags power in shorter intervals, so here, you can see that I was pushing anaerobic power levels for about 14 minutes, which was the whole workout execpt for when I faded in the middle of the last interval. By HR, it only shows 6:38.
This workout provides a good example of how the stroke based statistics of rowsandall can have errors that have a pretty big impact on shorter intervals. I parsed the workout data to select just the 4 work intervals, and the summary data from there was.

This is close enough for analysis purposes, and to provide a good definition of work and rest strokes, but for challenges, you definitely want to use the PM directly.
Tomorrow: 10 min warmup, 40 min steady state, 10 min cool down

Yes, I have to think about pacing this one. Is that 2k+5sec, pace-wise?
I think it’s more like 2K + 2. I bet that my 2K is right around 7 minutes right now based on how I felt in the first interval. And I think I could have done 1:47 for all the intervals, if that’s what I started with.
