I totally get the problem. It is not lack of literary resources or ability to assimilate the information but, in my case, the lack of a database of athletes' responses to programs based upon athlete type, goals and personality. In other words, tactical weekly training plans are based upon experience with many athletes and how they respond. Hence, I read Friel's stuff and others and could not turn it into an operational racing and training plan for myself. Hence, I hired a coach.

My take is that it is not easy to do and many coaches use a coach for their racing.

What I suggest is that you take the training plan and database that you have from the previous three years where you had a coach and lay that out. Then put in the races / events for the upcoming year and see how that compares with the past.

Based on your response to various weekly training routines, adjust the old program to accommodate the new racing goals.
