I enter Subjective Effort and Mood for my run in Garmin, but it is not appearing in TrainAsONE. Why?

You're correct, this data does not currently appear in TrainAsONE. The reason is a technical one related to how Garmin stores this information.

The Challenge: An Undocumented Process

Garmin does not currently publish details on how subjective data like 'Subjective Effort' and 'Mood' are recorded within an activity file. It is a private and undocumented process, meaning there is no official way for third-party services like ours to access it.

Our Progress & Next Steps

The good news is that our development team has successfully reverse-engineered this process, meaning we now understand how to extract this valuable data.

However, as of October 2025, we have not yet had the development resources available to implement this capability on our live platform. Please be assured that integrating this feature is a priority, and we will do so as soon as is practically possible. We appreciate your patience and look forward to adding this functionality.
