Track and field athletics are not the same as "sports", which is a term to cover all sports including team games, cycling, swimming, equestrian, sailing etc.
I started thinking about this when my neighbor, an impressive athlete, insisted that she hates sports. I asked whether triathalons weren't a sport and she said that to her, they really weren't -- that even though there might be hundreds of people in a race she is really competeing against the clock and against her previous preformances.
