Plan Builder and Confusing Adaptations Recommendations


I have been using Plan Builder for while now and haven’t noticed something like what I am experiencing lately. I just started up a new Plan for an A race in June.

My first few workouts have been endurance based and fairly easy. I have either chosen easy or moderate for my post ride rating (1 hr in length). These were all well below my current Endurance score so were initially shown as Achievable.

The confusion for me is after choosing Easy or Moderate, plan builder immediately wanted to drop the intensity levels for the next 4 weeks of Endurance workouts in my plan. I know I could just not update the plan, but I’m trying to understand what the logic behind the AI is. Its definitely not what I would have expected.

Anyone else seen this?
