What do the TrainingPeaks workout numbers mean?

As some of you are not as familiar with TrainingPeaks, I made a video explaining how to read the numbers and main chart for a given cycling workout, including:

  • How to understand the workout chart
  • What the main numbers mean: Training Stress Score (TSS), Normalized Power (NP), Intensity Factor (IF), etc.

@mapmeister please see above for the video I mentioned to you- how to read workouts in TrainingPeaks

This was SUPER helpful! @Coach_Theia Thank you!

@Coach_Theia The system wouldn’t let me post again to the other thread :rofl: but I’m hoping you can shed some light about something that bugs me about TP. Today, I had a VO2 workout on the books but had to move it to tomorrow. As soon as I moved it to tomorrow, swapping my off day, my Fitness/CTL dropped 2 points. Why wouldn’t my CTL be based on what activity I have actually completed (as if I don’t have prescribed workouts loaded), rather than trying to predict the load and showing me an inflated value? Thanks!

HI again group,

looking at the calendar I noticed a pattern, in all my workouts I was above the planned T score and it is always red, even if the workout appears green on the calendar.

What is the T score and what does it mean to go above it?

Thank you,

@Chiara I moved your question here because, even though you are asking about T-Score in Today’s Plan, that metric is very similar to the TSS Score in Training Peaks (which I explain in the video above).

If you hover your mouse over the metrics in Today’s Plan, you will see a brief explanation of what they mean:

So the T Score is a composite number that takes into account the duration and intensity of a workout to arrive at a single estimate of the overall training load and physiological stress created by that training session. Nevertheless, it has its limitations, as explained in the video above.

When it’s red, it means it was not as close to the estimated TScore for that session (either up or down). When it’s orange, it means it was close but not exactly there.

I never worry about these, as often times the difference between planned and completed scores have to do with rest intervals - which are not meaningful in a high intensity workout.

I find my actual T score is much higher than prescribed in Today’s plan but closer to that given on your training peaks video. Is that normal?

@Pippajgraham is your threshold the same in Today’s Plan and Training Peaks (and Zwift)? Unless the power on the intervals is way off, there is nothing to worry about.
