Over the years i’ve noticed that my general exhaustion and required recovery time correlates closer with accumulated fatigue than purely TSS. That seems true even though TSS does contain an element of intensity in its calculation which gets reflected in ATL and TSB.
I’m wondering how useful the addition of “time in fatigue zone” would be? Something like
Hrs in “High Fatigue” (W’ bal < 33%)
Hrs in “Medium Fatigue” (34%< W’ bal < 66%)
Hrs in “Low Fatigue” (W’ bal > 67%)
for every ride. I suppose it might better reflect the effect of HIIT efforts on than just TSS?
These metrics would not affect the PMC chart, but they would be helpful in the planning process because they’d make recovery time required after a planned workout more accessible if visible in the training plan.
I know Work above FTP is already available and is a very useful metric.
So, this might be a bit of overkill …?
