Ok, "recharge" is a pseudonym for "recovery" in your vernacular. You wrote it, not me.

It depends on one's definition of base. I have the flexibility to do decent volume outside during the winter. If I was on a trainer in the basement, my "base" block would look different, with more intensity. Ex-cyclist addressed this notion in the post I replied to. The amount of sweet spot and sub-threshold intensity that I can manage is probably greater than most. Likely more than most triathletes do during race prep, I do during winter base. So that program works for me, but might not for you or someone else.

Further, the notion of high intensity work eroding base--and the need to return to it after a block of racing--is absurd, IMO. Train, rest/recover, race, rest/recover, race some more.
