Chris,
I won't give you advice because I'm not a leading light here. But I'd refer you to a post done by Taras (probably a couple of years ago) that detailed "Layered Track Training" that I thought was one of the most useful things I've read of the many, many useful things I've read on this forum from people like him, Carleton and many more. Taras seems to pop in regularly, and maybe if he sees this he can link you to that, or I can drop in the text that I saved from it.
