Pl include cadence as a requirement in the workout creator. This would be a constant on screen display but would not control the trainer.
Also, please include the ability to display messages (eg stand, sit, sprint) at certain times in the workout.
thanks,
I don’t believe ERG mode in general *can* control cadence, and at the very least it won’t in Zwift, so you’ll need to moderate that yourself.
As for messages, you can include your own custom text prompts by using the bottom box in the custom workout creator at the point you want the prompt to appear.
