Just horrible. The first 20 minutes were awful. The second 20 were worse. I think I am not completely better. In any case, I need to dial back the intensity of steady state sessions to keep them as productive as possible.
First 20 minutes: Although Hr and lactates are not very well correlated, generally, I need to have the last 5 minute avg HR to be under 140 to have any prayer of the lactates being below 2.0. Obviously, that did not happen today.

Lactate test at end of 20′ –> 2.5mmol/l (way too high)
Then into the second 20 minutes. I should have slowed it down, but I want to play around a bit with different rates and pressures.

After that mess, I setup and did a 3 minute rate ladder for video analysis
