Would this work?

Are you using a computer or a phone/tablet? If using a pc I just use two ant sticks and connect to both programs simultaneously and it works quite well. Not sure of an easy solution for mobile users.

Just a note, keep this for your personal use, don't make any workouts you transfer from trainerroad to zwift public or share them. TrainerRoad's workouts are their intellectual property and sharing/copying without their consent would be against the law. They're pretty active on here, so they'll probably sniff out this thread and reply with something similar, but just thought I'd mention it.

Can 2X20 be intellectual property?

Certainly not.

Though, we do have a claim against people sharing workouts that are more obviously the property of TrainerRoad. Like the entire workout library for instance, or any of our training plans. Which, unfortunately, people have attempted to do. :( But if you're a user of both, and plan to use the workouts for your own personal purposes, we can't stop you from doing that.

We try to make things as affordable as possible with our subscription being $12/mo or $99/yr, so if you're into using our workouts, we'd love to get faster with you! :)

It's a real bummer we have to do this, but if anyone sees someone sharing our workouts please reach out to us right away at support@trainerroad.com. Not only is it unethical, but we believe sharing our library is a copyright violation. We'd really appreciate you letting us know as we've put a lot of hard work and energy into getting these workouts right for you all.

Thank you everyone!

P.S. We appreciate you mentioning this as well 'jarret_g'!

Just so you know, I had no intention on sharing any of the TR workouts. For my own purposes, I just wish I could run them in Zwift. Your workouts are better, but for me, I am a little more engaged on Zwift. I love TR and definitely have better results from using TR than Zwift, where I usually end up just riding around without purpose.
