So I'm in the adaptive training thing with trainerroad, kind of just putting faith in their machine learning and see where it takes me. I'm wrapping up the first week of SSB1 HV and today I did the first substitute workout. Generally, the first Saturday workout for SSB1 is 2hrs with 3x20 @ 88-92-90% for 121 tss. This is rated a 6.6 sweet spot workout and I generally find this quite doable, especially since there are 15min z1 between intervals. But I did a 98tss workout rated a 5.5, this was 3x20 @ 88% for 90mins. I may do a vlog type thing showing how the plans change, don't know if people would find this interesting.
Anyhow, for tomorrow, initially I was suggested a 5.6 level/95tss workout for 90mins and after today (which I marked as a moderate effort), I was given a 5.7 level/116tss workout for 2hrs
Overall, I'd say the adaptive training is trying to keep things productive without pushing folks too far/too soon in the plans.
