Thanks for the input. Yes, I can definitely see that SSB2 at the end felt really “easy”, even the hard workouts. Especially VO2 and threshold, like Lamark and Leconte. Repeatability also went up. VO2 intervals are easily managable. Threshold keeps being tough, but I think that is realtively difficult for me. SSB now feels like recover almost.
Perhaps I should re-test indeed after a good night of sleep and food and rehydration (just to make sure).
