Training peaks recently added a workout builder feature that is very similar to the zwift one and just today released a feature that allows those workouts to be exported to a zwo file (http://help.trainingpeaks.com/hc/en-us/articles/115000325647). It would be great if this could be taken one step further and have zwift automatically query training peaks for the day’s workout and set it as an option on the start screen (rather than having to go into the select workout screen).
