Hi ap13,
I had the same thoughts etc.
I ended up doing maintenance first, will then dive into the racing weight followed by the 70.3.
My reason for doing it that way is that the maintenance plan is “easier” than the racing weight than the 70.3 (I will either do the 2 or 3 – depending on what I think I can handle in terms of timing).
I guess you could also think of doing a bike or run specific plan instead fo the maintenance plan and then do the racing weight plan?
