What is the real problem with TR / Wahoo? [Adaptive Training]

I’m curious how the Garmin and Wahoo fit files on Strava differ.

My Garmin Connect is configured to send completed workouts to TrainerRoad, TrainingPeaks, Strava, and RideWithGPS. Using the web interface for TR, TP, and Strava, I downloaded the FIT file and found:

  • Garmin Connect, Strava, and TrainingPeaks have identical files
  • TrainerRoad FIT file has less information, and replaces speed with EnhancedSpeed (whatever that is) and at least one other edit mentioned below
  • my 1 hour outside workout from Monday 5 July 2021 has the following dowloaded FIT file sizes: 240,353 bytes original binary FIT file from Garmin and Strava, 128,707 bytes TrainerRoad, and 115,727 bytes from the compressed TrainingPeaks download (gunzip)

A few things I found interesting with outside workouts and the TR FIT file:

  • TR deletes information that I want, making it unusuable (for me) as an archiving tool, for example TR drops left/right balance, original workout’s intervals, power targets, and zones
  • TR lap messages curiously replace subsport “road” with “indoor_cycling”
  • TR does keep temperature data, just not displayed on TR completed workout UI

For those with a software background thought that info might be of interest.

Back to the topic at hand. Would be interesting for someone to compare the two FIT files from dual recording a TR outside workout. Someone with a Garmin computer/watch and a Wahoo computer.
