You mentioned trainerroad at the start, why not just load the Short Power Build plan? It's pretty much what hippy has prescribed but with the structure you want written down.
I mean, yeah, if you've got £10 a month, TR takes out a lot of the planning aspects. If you like their VO2 stuff. Every time I got to their VO2s I'd just bumped my FTP and then failed to hit any of their targets so just went back to sweet spot stuff. I'm not racing HCs though.
