Hi @Tobias_Kopp, Welcome to the Zwift Forums!
Fernanda here, part of the support specialist team at Zwift.
Thank you for using this space for your concerns regarding the training peaks sync, as Paul shared, this feature started in game version 1.66.0, in which TrainingPeaks workouts now include the next seven days of workouts, these are available in the TrainingPeaks custom workouts folder.
We are hopping this allow a better experienced for all our members!
Ride On.
