I have a weekly spirited group (1+ IF e.g. https://www.trainerroad.com/career/stevemckinney/rides/56294054-dtb-great-falls). Which weekday workout should I replace, the VO2 Max or Threshold?
Background: I’m 41 years old and assume I can benefit greatly from VO2 max. But the ride has plenty of VO2 max rolling hills and finishes with a 20 min Threshold paceline on the flats. I’m moving into the Build Phase and plan to do GBLV. This plan has only two weekday workouts, VO2 Max and Threshold.
