How old are you and how many TT miles you got in your legs? Do you know how to TT?
If <30 male, I think many could in a year of < 7 hours a week of focused training. Not including diet and sleep in the training part but that matters.
If you are north of 40 you likely cannot recover from 14 hours/week if you are just starting out. You might dig yourself into a hole - the more you train, the slower you get.
