# 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 wouldnâ€™t let me post again to the other thread but Iâ€™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 wouldnâ€™t my CTL be based on what activity I have actually completed (as if I donâ€™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

@Chiara I moved your question here because, even though you are asking about T-Score in Todayâ€™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 Todayâ€™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 itâ€™s red, it means it was not as close to the estimated TScore for that session (either up or down). When itâ€™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 Todayâ€™s plan but closer to that given on your training peaks video. Is that normal?

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