Soft 8.20 no HIIT

I created a HIIT workout and could send it to my 945 and sync. I then selected the HIIT activity type in the watch, selected Workouts and could select my workout.

Could you describe your issue in more detail? Maybe a step by step with exactly what you do and what you see?

Ok so I take a workout from Garmin sync and nothing but when I put it into calendar as an event I see it? 
this same with any Garmin workout I can’t see as a workout but I see when put into calendar 

Can't you start it from the Workout menu for the activity?

When you select the HIIT activity type in the watch do you see the three HIIT types: Free, HIIT Timers and Workouts?

I know that no I can’t see there 

But you see it if you add it to the calendar and then selecting the HIIT activity type, selecting Free, Options, Training->Training Calendar?

Yes I took it from Garmin ok I try reinstall watch and I see thanks for your help 

Strange. i asked the same this week and somebody told me that 'running workouts' was not possible. Now ik noticed that it is.

HIIT came with 8.20 which was released this weeek.

Have you sent the workout to the watch? You need to Send to Device if you wish the workout to be "permanently" stored on the watch, making it possible to start it from the watch regardless of whether you have added it to your calendar or not.

If you only add your workout to your calendar and sync, I believe that the workout will be there only during the day of the planned workout and then it disappears again.
