Gotta agree with your x-coach on this one. Periodization got a lot of play for a long time but I no longer buy into it and the more you research its roots the less convincing it is for endurance athletes.
Working with the Performance Manager and listening to feedback from folks on this forum I've moved to taking rest when life intervenes or my CTL ramp gets too steep but not based on any preplanned periods. I also agree with his feelings on "gradual improvement based on high intensity training" with the caveat that HIT means different things to different folks. If he's talking about SST, L4, L5 and above then I agree. If he's talking about the kind of plans I've seen online that work only L5 and L6 with 30 second to 4 minute intervals then I'm not buying it.
I've become a firm believer in a Tempo/SST/L4 base topped off with a small amount of L6 and L7 work as the racing season gets under way. Compared to old school LSD training that could be called "high intensity training" but it's still based on longer aerobic efforts like 20 to 30 minute aerobic intervals. It's all about training the appropriate energy delivery systems for your target events and for general road racing, tt's and crits that starts with the ability to fuel your muscles at threshold pace(FTP) for long periods. 30 second to 2 minute intervals just won't get the job done unless you're events are completely anaerobic. Sure that can be the icing on the cake when you've already got a big aerobic engine but you've got to work the systems you're going to use and you can't fuel your muscles anaerobically for a full RR or 40 K TT.
Anyway, you asked for suggestions, I'd build your base on SST/L4 work with some longer Tempo rides as your core aerobic fitness. When that's getting pretty solid then it's time to work in some of the real high end work that can make the difference during crunch times. That's a form of high intensity training but not the make ya puke work some programs advocate.
Good luck,
