Combination of TrainerRoad and Xert

To that end, maybe i need to quit using ERG except for LSD… because if i’m just riding to ERG during my SST/FTP/VO2 workouts, i’m not able to adjust my efforts up/down such that the i can drain a desired amount of MPA or hitting the desired focus?

is this the hour power that I see in Xert’s model?

what is Garmin advisor? Just the training thing that I see on the garmin edge 830 head unit?
