A couple of thoughts --

Six months is a long time to be following a training schedule. With rest weeks built in, you'll probably be fine, but there's a chance you'll start to feel a bit burnt out after a while. So you might consider changing the routine at some point (such as switching the days you do certain things), especially for the rest weeks, just to help you stay mentally fresh.

If possible, do some training on the actual ride route, especially the hilly parts.
