I’d asked this in another thread and Coach Isaiah suggested the plans may be designed to have to target a specific range of power within a zone, so I stopped zone-i-fying the workouts first. Working to smooth power is a goal anyway, so I just roll with the Garmin targets as presented and try to hit the middle. I now just keep my zones taped to the stem when new until I have the z2-3-4 break points memorized to make sure I generally stay within the ceiling/floor of the intended target’s zone. Zones are specific but still fuzzy, if you drift momentarily slightly into the next zone the fuel/oxygen mix is still similar on a scale to the last few watts behind it.
