A couple of grips about Zwift is that even though one is theoretically doing hill climbs (not in a training package) it does not translate into being a better climber when one hits the real roads. This was evident last spring after a winter of unfocused Zwift riding. What a let down. Although I was a great pedal masher and could improve my average speeds on the flats.
Another regarding the Build me Up plan is that I don’t see much in the way of Zone 1 and 2 rest/endurance spinning. I have done three workouts and they just ramp up the difficulty and duration. As a result I am introducing my own Zone1/2 to keep from frying myself. This may counter the purpose of Build me Up but a senior does not have the infinite reserves of a 20 year old. I know it is based on FTP but recovery takes longer with age and it would be nice if that was factored into the plans.
