Do you or have you ever read books about the Olympics? About sports in general? Fictional ones? Or non-fiction? Or both? Do you consider yourself a sports fan?
I've been staying up waaayyyy too late this week watching gymnastics and swimming. I don't consider myself a sports fan, but I do have several events through the year that I always watch: tennis (the US Open and Wimbledon -- did you SEE the men's finals this year???), baseball (the World Series, especially if the Yankees are playing) and parts of the Olympics, summer and winter (not much interested in track and field).
I don't read books about sports per se unless it's an incidental part of the story -- like The Brothers K by David James Duncan, which is about baseball, but so much more. One of my all-time favorites.
