Here is a link to the VO2 intensive thread if you’re interested:
Also to expand on my prior reply, make sure to keep VO2 in the context of your overall plan. If doing VO2 work starts preventing you from nailing your plan’s key workouts, then I’d back it off a bit, maybe consider opting for “-“ versions of the VO2 workouts. Until your body adjusts make sure you have adequate rest/recovery following the intensity to make sure you’re ready for key days.
