Cheating at sports

NPR article about professional cyclists cheating

I can understand putting a motor in your bike, if you’re just a person who likes biking and is getting a bit old in the tooth (to help you go up on some of those steeper hills). But, if biking is your “profession”, and you then make a conscious decision to cheat (by using a motor), in order to win? Now that, boggles my mind. I don’t think I could live with myself, if I won a race by doing it this way.
