Registered Custom Workouts can be selected from "Custom".
If it is not synchronized with the latest information, please do Sync Now from settings.
Even in the free version, you can check the default configuration.
However, "Route Location" is effective only when the location setting is "Outdoor".
Distance data is registered by watchOS to Apple Health.
A interval of distance sample data is usually in units of tens of minutes, but it will be in units of seconds during workout.
However, we have confirmed activities that registration of distance data has a following behavior.
Zones excludes them from distance measurement.
Since these are the specifications of watchOS,
it is impossible to clearly distinguish which activity applies to the above. Please understand.
Below is the reference information we tried with Apple Watch Serires 3 + watchOS 4.2.
Above activities are "1. Distance data is not recorded".
Other than above activities, it is possible to update to the correct distance by doing Re-collect sample data after measurement.
It may be wrong info depending on your environment of use or contents of workout.
Please use it as reference information after understanding.
