Hey Schmidt,
In order to create outside workouts that exactly match their indoor counterparts, it requires a Support Agent to go in and manually build the outside workout interval by interval. For many of our workouts, this has been done, so when you select “Outside Workout” it will push a nearly identical workout to your head unit.
That being said, we still have a list of Workouts that have not been given this exact 1:1 outside workout variant. For these workouts, we have a one-to-many relationship, meaning that we link many indoor workouts with a single outdoor workout variant that achieves a similar training effect. We know this is not a perfect solution, but it is a temporary solution since we are working through the list of remaining workouts in an attempt to bring our entire Workout LIbrary up to the same 1:1 standard.
I hope this clears things up, let me know if you have any further questions
