Those “bail outs” are useful if you consider that for a loooong time, they were the only time that idea of salvaging an active workout (vs quitting all together).
Most of that text was written well before the podcast and active use of the blog or other resources existed to share those ideas with people. So they are very good in that light, as an educational opportunity.
With the advent and proliferation of the podcast, that text may be less necessary. But I still see value in that they are added for times in particular workouts that seem to have the most frequent issues of completion.
It’s a fine line to walk to be supportive vs planting a seed of doubt. I do it all the time. I use positive thought “I got this” and such in the beginning and middle of intervals sometimes. It’s crazy how fast an “I can” turns into “No way I can” and that’s purely internal.
So getting the text right for everyone, in every workout, in every stage of training is a practical impossibility. I like having it there, even though I may use it less now than when I first started with TR. But I think the text overall is so helpful to riders new to this level of training.
