Outdoor training

When riding outdoors using trainerroad workout. What is the benefit of selecting outdoor option as opposed to selecting the indoor option? I just selected the indoor option and used that for the outdoor workout and it worked great.

Some of the workouts have been tailored to work a bit “better” outdoors due to environmental reasons, etc. If you compare they are usually slightly different than the inside version, but they are designed to work the same systems.

Thank you for taking the time to respond. Appreciate the information.
I really like your YouTube videos

How did you get the indoor option to your head unit
