Hey Kat – the only silly question, is the one never asked 😉
The basic coaching is more of a “pre-written monthly plan” where the coach writes 4 weeks training according to your needs, objectives, and availability.
Then the personalized plan is written 1 week at a time, according to your regular feedback. And of course, for your needs, ect.
My suggestion is to start with the personalize plan, get going right and make the most out of it. This is particularly good during or going into the racing season. It’s also when your coach has to work the most and there’s greater communication.
Then once you get into a routine, or when the major races are done. You can drop down to the basic plan. As it will also be lighter maintenance for your coach, as he gets to know you better!
