  Austin has a nice and popular trail where many runners train along town lake so back when I was jogging, I would occasionally gets passed by a really great runner (like our local Gilbert Tuhabonye[1]). It's really awe inspiring to be right there--like the difference between only watching Andy Roddick serve at 150+ mph and what I imagine its like trying to return it.
