Does the outside workout option only work with Garmin computers, or will it work with Wahoo units as well? Do I need to download an update to my TR app on my computer
Currently, outside workouts do not push to head units.
We are working on finishing up the Garmin implementation, and then we plan to release Wahoo support sometime afterwards. The exact timeline is not set in stone because we have to work in cooperation with other companies, so we can occasionally hit bottlenecks that take some time to resolve.
Any updates or developments will be shared in the Announcements section here in the forum 
Good news, thanks for the update Bryce!!
