I’m 56, weight 174lbs and 5 foot 8. I’ve been Zwifting for about 2 months now and have mainly been doing FTP builder workouts. I’ve got a dumb trainer (Cyclops Fluid 2) I’m just onto week 3 of the 10- 12 week FTP builder and have noticed that my “zones” are nowhere near where Zwift suggests they should be. Last night I did the Week 3 Day 1 ride which suggests I should spend 29% in zone 1 and 71% in zone 2, but in reality I spent the bulk of my time in zone 4 with some time in zone 3
I try to average a cadence of around 90 and just about manage to hit the wattage targets and generally feel that I’ve had a workout without it being “too easy” or “too tough”. In fact, it feels just about right! But I can’t help being slightly concerned that I’m not doing it right. I’m getting “results” in the sense that my initial FTP test was 124, then after the 6 week beginner FTP builder It went up to 156.
I guess part of being 56 is the tendency to over think things!?
