Hey @jackriddle2,
Good questions. Welcome back to SUF!
As a coach, I would recommend you start off with the FTP block, then MAP just to get ease you ( a little) into the intense rides since you haven’t done them in a while. Physiologically it gives your body a chance to adapt better to the intensity density of the workouts. Mentally it helps by not having to question your sanity when your have Nine Hammers in the 2nd week of your plan.
cheers,
