Running power measurement can come from different inputs: apps (e.g. Kinomap connected to a treadmill), Stryd, Garmin / Suunto / Coros, etc, with different scale.

However, TrainingPeaks allows only a single running power threshold, and inserting multiple zones in the same list (max 10 zones) does not allow an accurate TSS calculation, which depends on FTP/CP.

The question is whether it would be possible to have multiple power thresholds that can be associated with running depending on the measurement device being used.
