Hi, I am just curious. Theoretically in case somebody want to prepare “Ironman Plan – Level 4 or 5”:
Such plan level 4 or 5 will have only increased total volume for each intensity?
[e.g. +20% for low intensity and +20% for high intensity intervals]
In order to stay closely aligned with 80/20 structure.
OR
The plan will be with increased low intensity part only?
[e.g. +30% for low intensity part] In order to reach desired TSS.
OR
The plan will be with added intervals of high intensity only?
Just wondering how to achieve some numbers, based on elite ultra-triathletes declared training volumes 20+ hours a week and 1000+ TSS a week.
