So right now we have “single block mode” (base or build primarily) soon depending on the weeks until your event or desired goal date we will introduce multiple blocks. This will support up to 28 week “plans.” Because 16-20 weeks is generally about as much as people can handle of a build and peak period before burnout, if you go longer than 20 it will include a base period.
Just as an example many people burnout or get very tired after a hard ~12-week TrainerRoad plan, our plans start and generally stay easier so they can be sustained longer as well as more comfortably. We don’t know about TR’s adaptive training but I would say PROVEN science is on our side for work/efficiency/results compared to TR’s old plans. Many people have had great success with TrainerRoad so I am not trying to bash them, just saying Coach Jack takes a different approach (sorry I know I am repeating myself).
