Yeah, problem with that is if you’re time limited… straight Z2/Tempo base periods require double-digit hours per week to truly effective. I’m going to tough that out for three weeks, riding four days a week at 10-12+ hours of straight Z2, but lots of mornings up at 5am to make that work. Still, the benefits can be big…
For me, it’ll be more a progression of:
Long Z2 → Tempo progression + 1 long ride → SST progression + 1 long ride/fatigue resistance ride
And I think that’ll be my base. Tempo progression will likely include 1x SST workout each week; SST progression will be 2x SST with another tempo ride if I’m fresh enough. When I tried to do three SST workouts in a week I was very hit and miss this last offseason. 2x SST + 1x tempo was sustainable.
In the end, it won’t be a true SST progression anyway since I doubt I will be doing 2x 2hrs of SST this season. I think that much time will end up taking a lot out of me. We’ll see.
