@Will_Peters yes. They said this was normal. I happened to post to the forum, too, as I was really confused since the plan also included 5 weeks on and 1 week off.
Coincidentally, this was also the day they had just announced Master’s Plans. I scrapped my plan and re-added with Master’s using Plan Builder. I’m now seeing very good week-over-week improvement and am able to add back a harder day as I feel motivated and able. Need to manage burning out especially this early in the winter training season.
I’m now a bit more hands-on with my plan, watching what is being recommended and then upping workout PLs as I regain my base and fatigue resistance.
(EDIT: I missed that @AussieRider is questioning VO2 for Master’s. Missed that sorry. Would still recommend keeping your hands on the plan while AI makes adjustments. The thread below still has good suggestions)
You can see the previous thread here. @mcneese.chad has some good advice there as well. Hope this helps.
