documents: #Person1#: Are there running groups in this neighborhood? I've been wanting to run in the mornings, but I don't like to do it alone.
  #Person2#: Yeah, there is a group that meets at the park a few blocks from the university. They meet every Sunday morning.
  #Person1#: I should join them. I wonder how far they run.
  #Person2#: They usually run to the river, about a mile I think.
  #Person1#: No, that would be about 3 miles. I usually only run, too.
  #Person2#: Well, maybe running with other people will give you more energy. When I bike with others, I always go faster and farther.
