You ask some very good questions!
As far as the full distance tri plans go, I wouldn’t recommend putting them on repeat all year. The volume is probably just too high and I think you’d probably burn out, and if not, you’d probably at least get bored for lack of variety.
The progression of the full distance tri plans follows a fairly traditional periodization scheme in that they begin with technique sessions and lower intensity sessions that progress in volume (although there are still high intensity sessions mixed in), and progress to higher intensity and longer sessions throughout the training plan. But this is all done within the 16 week program, so it does still match the format of the cycling programs because you’re not spending 3 months on base building, etc.
So instead of following the full distance tri plans year round, I think the best option is this- and I’ll just use the start of the year with your target full tri later in the season, like September, for example. In January, you could start with an Olympic distance tri plan with strength integrated, then go to a half distance tri plan with strength integrated, then finish with a full distance tri plan (no strength) and that timing would lead you straight into race day. That method will give you a consistent tri training schedule with high intensity sessions throughout, but progress in volume over the course of 40 weeks, getting you race ready for the full distance when you need to be, and hopefully without getting burnt out.
We do have short term focused plans for swimming and running on the radar, but they may not be ready for a while yet.
Hope that helps and happy training!
