#Person1#: I've been wondering how to start running. I want to run a marathon and I know you're a good runner.
#Person2#: Well, you need to start out slowly. See if you can run a mile without stopping and then start increasing your distance.
#Person1#: OK, do you think I should run on a running machine at the gym or outside?
#Person2#: Well, it depends on what you like. Running inside is nice, because you can stay at a steady speed. But outside is nice too, because you're surrounded by nature and fresh air.
#Person1#: Maybe I'll try running outside first and see how it feels.
