I'm pretty sure that a lot of us training with power meter would also need a cadence target during intervals. For example, during the winter I have to build up my strength so I have to meet a certain power range at a certain RPM. Every time I train I forget about that RPM value, also because the intervals are often quite a lot. I understand there is no possibility either to edit the workout view of my edge 820 to add cadence range neither there is the option to add a third target to a workout phase.
Having the feature to specify a TIME + POWER RANGE + RPM RANGE targets and to see those values in the workout view would be fantastic.
As a second, I guess easier, option, it would be good to use the "step notes" feature to write down the RPM RANGE. Currently, while building my workout, I fill in the RPM the the notes field, but the device is not showing those notes. A data field would be perfect, so I would create a custom workout page that would include the target power, current power, current cadence, lap time and very important notes.
Having the feature to display step notes or at least workout note on the 820 would be much appreciated.
My Fenix 5x is actually capable of displaying the notes, so I'm arguing why this couldn't be achieved also on the 820.
Another solution, would be to release the remote display feature on the 820, hoping that it would be possible to send the notes field from the F5x to the 820.
Thanks for reading and crossfingers....
