Riding at that low rpm (40-60) is something the OP will also have work on in TR. It seems, the OP likes higher cadence. That low rpm will tax the OP if it has not been trained.
OP, I do LV workouts so that I have the flexibility to add rides and to move rides around during the week. I can’t always ride on the same day of the week and I want to do outside rides (would be doing more outside rides if not for this pandemic). Life throws curve balls each week and I have to be able to improvise, adjust and overcome.
