For me it is still showing as min/km to this day. I just think Garmin uses the same metric used for running pace, which is min/km. I don’t know if the Garmin API would allow @david to specify the pace metric unit.
So I decided to group every combination of work/rest steps instead by doing the following:
1x
- "Warmup in Z1-Z2" 200 meters 80% pace intensity=warmup
- Rest 10" intensity=rest
Mind the 1x and the double quotes.
That shows nicely in the Garmin watch as 1x200 (0:10), and adds the quoted info in the instructions.
It works the same way with 2x, 3x, etc.
It then removes the weird pace info, make the sets clear, and the intensity is left to be informed in the instructions of the steps. Not ideal, but less confusing at least.
Look below (Fenix 6 Pro) how it appears in the “View” option of the workout:
What is shown when you enter the workout, before clicking the start button:
What you see during the interval:
And how it shows briefly when you change to the main set, after hitting the button lap:
The main set you see has been built the same way as described above.
I hope it helps you and others to come. It took me a long while of researching and testing to get to this state.
