Hi NmcFlower,
The workout library workouts from our website match the 80/20 Triathlon Book and our TrainingPeaks Library. Here is a section from our Q&A’s on the website that helps to explains this:
Why are the workouts in the 80/20 Workout Library different than some of the workouts of a similar name from the book 80/20 Running?
While the current workout library was inspired by the original run workouts in 80/20 Running, the two sources are considered different series and evolved separately. For example, while it is normal to assume that the Speed Play Run 4 workout from the book should be the same as the RSP4 in the library, the two workouts are not identical. You may be able to find another workout in the 80/20 workout library that is identical to a workout published in 80/20 Running. For example, the workout library RSP5 can be used in place of the book’s Speed Play Run 4.
If you are using a training plan from the 80/20 Running book, follow the workout structure from the book, or find a workout match in the workout library. If you are using an updated 80/20 run plan from this site, the workouts are identical to those in the 80/20 workout library. Additionally, the workouts in the book 80/20 Triathlon and triathlon plans on this site are also identical to those in the 80/20 workout library.
