[Sort of OT] Walking workout distinction
in Workouts what is the difference between Outdoor Walk and Indoor Walk? I understand the difference between outdoor and indoor, but is there an actual difference? Walking is walking. Does an Indoor Walk presuppose a stationary device like a treadmill? So if you're working through a large indoor area, say a giant airport like Istanbul, Indoor Walk or Outdoor Walk, or doesn't it matter?
Just curious about this.
Thanks very much.
