Jury’s still out for me, but in the month I’ve been following a TR HV Masters plan, the Endurance power targets have been right at the top of what I would shoot for on “z2” days, so they’ve been grippier at all durations. Having said that, I’ve gotten them done, and I think it’ll be an improvement. I’ve been good on my intensity days.
I think also that I wasn’t convinced on a fixed 3 on 1 off schedule as it seemed too “cookie cutter”, but those super compensation weeks are a great mental break I can feel my body responding, even when I didn’t feel wrecked coming into the week.
