Sure, I'll do all of these things, as I said.
I'll get a full 500m, 1:34 @ 32 spm (13 SPI) tomorrow, if I can.
Then, slowly but surely, I will work up a full 8 x 500m, 1:34 @ 32 spm.
Then, I will stretch this 8 x 500m to 20 x 500m.
No, 13 SPI is not hard for me to do at all.
Flooded with lactic acid with a HR of 155 bpm?
How?
155 bpm is middlin' UT1.
My anaerobic threshold is 172 bpm.
Sure, once I get to about 185 bpm, I will be in distress.
But as I mentioned, the goal with short TR intervals of this sort will be to avoid such distress entirely.
If I want to do 20 x 500m (3:30 rest), 1:34 @ 32 spm, I will need to keep my HR below 175 bpm at the end of each interval, and I will need to recover completely between each interval.
I think my fitness and skills are now up to it.
I suppose we'll soon see.
