Introductory workout for those joining Zwift's Fondo training plan. This is a welcome workout designed to introduce you to both workout mode and our new flex-time structured training plans. This workout is designed to help you get a sense if your FTP (Functional Threshold Power) is set correctly, though it is a good workout even if you're already confident in your FTP. An accurate FTP is critical to getting the most out of Zwift's structured workouts.
