A few months back I accidentally changed my FTP setting on the workout screen (thanks ATV interface). I believe it used to auto adjust to whatever Zwift detected my FTP to be before that. Now it’s stuck at whatever I last set it to. Is there a way to make my FTP auto set to what it is in my profile? (Did it ever do that, or I am misremembering it?)
Thank you, but it’s currently set at 210, has been for months, and my profile says it is currently 233. When I set it to 210 I was in class D, now I class C so I know it has changed. Could it be bugged?
I will change it manually to 233 now, and see if it changes next time my FTP changes in games.
Try doing a zone 2 warmup and then 3 minutes at max effort and see what happens to your zFTP. Mine went down by around 25W. I used Volcano Climb with Trainer Difficulty at zero, but any hill with a reasonable approach will do.
I often do searches when I have a question, but they often lead here, not a FAQ.
In this case while the z made me question what the difference is, the description on the profile page made it sound just like regular FTP. So I think something in the description on the profile page could have saved my confusion. Or maybe list the estimated regular FTP on that same page?
There are many metrics available for tracking fitness and fitness progression.
None of them were designed to categorize riders and most of them will not agree with each other.
Just let Zwift Racing categorize by the method they use.
For workouts, select 1 metric and track it.
I use the eFTP provided by Intervals.
Zwift does calculate an FTP based on 95% of best 20min effort and that’s fine.
You can use the zFTP that is calculated from your Critical Power curve.
You can also do periodic FTP or RAMP tests (again, one or the other).
All these will be different and you will have to manually set your FTP for most.
I don’t like the FTP test or the ramp test because they are hard and not fun.
I prefer to the eFTP because it takes in races, workouts and social rides.
I also think I can continue to use it for outside training
