Since the removal of the TrainingPeaks ConnectIQ I have enabled the calendar sync feature. For the most part it appears to work in that 'most' Bike and Run workouts are synced to GC and show up on my watch/head unit. There are however a number of bike workouts that do not. I've tried reading through the FAQs on TrainingPeaks which says eligible workouts' however it does not specify what is considered eligible. (NOTE: it does note that Swimming workouts are not synced though this is not what I am trying to do).
There's no obvious reason why one workout would sync versus the other. These are not particularly complicated, or multi-step, workouts.
Has anyone else experienced this? If so, have you found a solution?
