Kina, thanks for your post, and you and I carried on this topic offline through e-mail. I’ve posted the core of our correspondence here for the benefit of the community.
“To work with an Apple watch, the Stryd solution, which requires the actual device, is required to sync with TrainingPeaks
Your completed workouts will still sync from Apple to TrainingPeaks, but planned activities from TrainingPeaks to Apple requires the complete solution.
TrainingPeaks has significant benefits other than analysis. Smartphone, planning, notifications, and structured workouts.
The structured workouts feature is pretty amazing. I recognize it’s more cost to get a compatible device (Stryd or Garmin), but the ROI is well worth it. Once you use it, you’ll never want to go back.”
