Yup. Same deal, I did SPBHV and SSBHV and the last few minutes of the ramp tests were becoming so terrible I had to switch to a different protocol! The saving grace is that VO2 fitness comes along relatively quickly so it shouldn’t suck for more than a couple of weeks.
I will, however, admit to doing a bunch of O/U workouts on purpose (wtf?!?). I did them the previous year before joining TR and OMG were they horrible! Ha! So I bit the bullet hard and trained to turn that weakness into a strength. If you took a poll of the most loathed/feared workouts it’d probably be a 50/50 split between O/U and VO2max.
