Hi @ntdeck I think the TR swim as well as run workouts are spot on. I use training peaks and have built my yearly plans in the past around yearly and weekly TSS. I’ve had to calculate weekly TSS for each respective discipline as well as ramp rates for the correct build each week which took a ton of time and effort. The two training parameters that lead to an overall gain in fitness are volume and intensity. I will say that following the trainer road plans to a T, the intensity and volume are spot on to where it should be. Of course there is a constant debate on the methodology of training i.e periodization, reverse periodization, polarization and some may find some more beneficial than others. The TR plans have a great progressive build throughout the base, build and race specific phases. There is usually 1 V02, 1 tempo and 2-3 low aerobic sessions each week in each discipline. From a general training standpoint, the hard workouts should be hard and the easy workouts should be easy. The answer is usually never adding more intensity. People do not emphasis the importance of low aerobic zone work enough. The time spent swimming, running and riding at these low zone 2 paces are equally important at building fitness as other key sessions. I would say however, that there should be more muscular endurance workouts incorporated into the plan such as hill sprints. Anyway, that is just my 2 cents.
