Christel’s Two Cents:
I thought I provide some info on creating structured Workouts in TrainingPeaks and how to get them onto TrainerRoad or Zwift for a trainer ride or to Garmin Connect and your Garmin device for outdoor workouts. Note: I do not have a Zwift account, but I included a link to a page that explains how it works on Zwift.
