80/20 Triathlon

I like Matt Fitzgerald and his books, like Race Weight and How Bad Do you Want.
In this book, he convinced me to try 80/20 approach to my back to Triathlon training after my 4 years break from it.
4 stars just because it feels a little light on the breadth of the topics however it covers all the aspects of 80/20 training including how to setup your own training plan and 4-5 plans for different Triathlon distances.
