Great to see so much training going on. Spider, 2 solid sessions. Your HR improvement on the 30R20 is spectacular, while the rate ladder is tough with 10' at each rate, well done getting that far!
Mat, excellent improvement, that final 6' was deep in the pain cave I'm sure.
Eric, good solid session. Your HR recovers so quickly in the active recovery! As Mat says 2k is a tough one. However I would be a little cautious trying to maintain 6 x 1'r1' pace. Time intervals correspond to different distance intervals depending on pace. I can do 10 x 1'r1' at around my 1k pace! Unfortunately the only good pacers are nearly as tough as a 2k! My goto is 4 x 1k r4' where the average is about what I hold for the first 1500 of my 2k then increase the pace for a "sprint" finish. However to do justice in a 2k you do need to get "comfortable" at higher rates. The faster strokes need to be coordinated with your breathing. Irt is easy to maintain R30+ for 1-2 min at a time as insufficient oxygen can be compensated by oxygen debt. But beyond this it will bite you. I find 500 intervals with 2-3 min rest between works to "practice" the higher rating without pushing me to the point that my stroke falls apart (try 6 -

. Then you can try the 1ks, perhaps starting a bit conservative (your 170W?) then trying to make the second and third a bit faster (couple of Watts per interval?), while starting the last say trying to hold 180W for the first 700 then increase the rating for each of the last 3 100s. If your legs go to jelly, reduce the length of your slide, I sometimes do the last 50 - 100 with almost no slide and rating anything up to 50! - Good luck!
After yesterday's failed CTC, building to a long session of 5k intervals tomorrow night, I did my first wholly UT2 session for a long time, same pace as usual, but Max HR 80% (I know many use lower thresholds, but that feels right RPE for me!):
