The calculations are as follows:

- Load = (sec x Normalised Watts x Intensity) / (FTP x 3600) x 100
- Intensity = Normalised Watts / FTP

The software does it for you, so no need to try calculate it. Use the [workout builder](https://forum.intervals.icu/t/workout-builder/1163) for this.

Edit: _The words **Load** (TSS), **Normalised Watts** (Normalized Power) and **Intensity** (Intensity Factor) are used on Intervals, because the other terms (in brackets) are registered trademarks of Peaksware LLC._
