Interesting thread.
I was about to sign up for an adaptive MTB plan using RPE.
With TP every single recorded action is calculated and taken into account.
Now, I don’t mind my running not taken into account but occasional rides (volume, trips) are a must.
A training session after a 60 miles ride with friends needs to be adapted according to its TSS and IF.
I need to trust the plan to advance me, all data considered.
