I have been using Z1 for almost a year on Zwift (since the early Beta days) and according to Zwift ended with an FTP of 301.
Now I am 57 and stopped racing about 3 years ago so I always suspected this was an overly generous FTP and my cruising uphills made me think I was either superman or everyone else must be weekend warriors at best.
Last week I finally got the funds together for the Wahoo Kikr SNAP and not only was I not able to hold 300watts, I could barely even get to 200… anything over 150 was serious hard work for any period of time… On the Watopia island EPIC KOM I went from getting to the top in 24 minutes to needing over 50 !
Is it that Jetback’s power curves are completely wrong or is it that Zwift is misinterpreting the data. How can there be close to 70% discrepancy between Z1 and Wahoo power?
Perhaps Zwift could display whether someone is riding smart or dumb trainer to give a bit more reality to the whole experience.
