How do I take high speed images at long distances?

I have a Canon S5IS camera that I want to use to take pictures at sporting events, such as baseball games, football games, and especially auto racing events such as the Indy 500. What type of lens should I be looking at to produce a high quality image when what I’m trying to capture is going 220mph and 1/2 mile away? Do I need a lens at all? Thanks!
