Impossible to start a planned XC Ski workout

Hi. I also purchased the Forerunner 945 LTE. I just tried to plan a workout for my next xc ski activity and I encountered the exact same issue you described.

I'm considering buying a 945 LTE. Is this still an issue?

Hi. I would say it is not an issue anymore.

Based on the description of the original post from two years ago, it seems things have changed. I tried launching a XC ski workout today just for you. I attached a few pictures for you to follow along my narration.

In the Garmin Connect App, you can only create workouts for a limited number of activities. These workouts can be launched from their associated activity. For other activities not listed in the App, there is an option to create a "Custom" workout (see first picture). I created one called "XC ski HIIT".

If, for example, you try launching a workout from the "XC Skate Ski" activities, the custom workout will not appear in the list of available workouts. Instead, the watch will prompt you to create a workout in the Garmin app (see first half of second picture).

The custom workouts can be launched from the "Workouts" activity. When doing so, it will ask you to choose a "profile", which lists all activities. From there you can assign your workout to "XC Skate Ski" (see second half of the second picture.  

I was able to launch the activity, go through each steps, and then save it. It was saved as a "XC Skate Ski" activity as intended (see third picture). 

I don't quite understand why all activities are not available from the list of workout activities in the App. Hopefully, Garmin can make it more user-friendly in the future.

I hope this was helpful.
