Does TR's adaptive training model use objective ride data in addition to the post-workout survey?

Hi all,
I’m trying to better understand how the adaptive training model actually determines progression.

On a recent podcast with Hannah Otto, Jonathan Lee mentioned that TrainerRoad uses ride data to adapt subsequent workouts, while also emphasizing that athletes should stick to prescribed targets and complete the post-workout survey honestly. I understand both statements can be true. What I’m trying to clarify is: how much weight is given to objective power execution versus subjective survey feedback in determining future workout adjustments?

A few specific scenarios for example:

  1. If I complete a prescribed Sweet Spot workout, hit all power targets as written, but my heart rate stays relatively low (for example, never really leaving Zone 2), does the model recognize that physiological response and adjust future workouts upward? Or is progression primarily driven by the post-workout RPE survey once the workout is marked as successfully completed?

  2. If I complete intervals slightly above the prescribed targets (for example, averaging ~5 watts higher per interval) while heart rate remains stable, does the system factor that slightl overperformance into future adaptations?

I’m not questioning the effectiveness of the model. I’m only about eight weeks into using TrainerRoad, really enjoying it, and already seeing measurable improvements - so something is working. Overall i think it’s an excellent tool and simply interested in understanding more about how the system works.

We use all of the data you’ve mentioned, but I think it’s safe to say that power and RPE are really important.

We do use HR data as well, but I don’t think that we’d change all of your upcoming workouts if your HR didn’t perfectly align with what we’ve grown to expect, since it can be influenced by many, many things.

If you’re under or overshooting power targets, we’ll look at the objective power data when analyzing your ride.

Let me know if that answers your question. :slightly_smiling_face:
