@atoponce Yeah, I wasn’t sure if CPS allowed for a speed criteria, and didn’t want to re-read the spec so I just linked it for you. CPS is often used with another protocol CSCS (Cycling Speed and Cadence Sensor), which obviously does report speed.
When you finish an indoor cycling session, you can “edit the distance” for an indoor cycling ride. I never bother to do this, but if you use it to match what you’re seeing in an app, then you might get something you’d like, assuming it takes the “distance” and works out a speed graph over the session duration.
Out of curiosity, what do you expect to learn from “speed” you can’t learn with power data? I don’t know of a “FTS” Functional Threshold Speed aspect like there is FTP to make power zones. Do you think you’d use it as an alternative way to determine TSS?
