For workouts with elevation gain, training load is absolutely unhinged

    Hey Amy, 
    I'd be happy to provide insight here, but without seeing your actual training data, I cannot answer your question based on your training. For that I would recommend emailing our COROS Coaches for further insight on your metrics.
    Are you using Run or Train Run?
    The reason I ask is there can be slight differences in how TL is calculated based on which one you are using.
    Training load uses the TRIMP method to calculate a value. This means it uses duration (time in min) and intensity (HR or pace) depending on the activity.
    Road run:

    • this mode uses HR when you are running at low intensity (< threshold pace), but then it switches to pace when you are running at higher intensities (> threshold pace).

    Trail run:

    • this mode solely uses Effort Pace as the intensity.

    Sometimes what happens (especially with hill repeats) is that you're reaching zone 6 Effort Pace very easily, which pushes TL up very fast. If you were to use road run, hill repeats would be done lower than threshold pace, which means it would take HR as intensity, and HR takes time to adjust so you may just get a few seconds in zone 5-6. In other words, TL is much more responsive to intensities in the mountains when using trail running compared to road running, which usually leads to higher TL scores.

     With this information, I hope that helps you better understand the metric, and perhaps clarifies the answer to your question. If you feel that your data does not align with what I shared above, please consider emailing our coaches for further insight.
