Mountain biking is not cycling and trail running is not running.
How can I define new activity categories in Garmin Connect where I can, for example, take on mountain biking or trail running?
On the watch, for example, there is running and trail running, but in Garmin Connect both are combined as running.
You can also define the standard equipment for each category and that is not the same for running and trail running, or cycling and mountain biking. But without an additional category, it is treated as the same activity in Garmin Connect.
