I am a proponent of marathon race and runners. But as you said and pointed out correctly, some even prefer to cheat. But how come they do so in this highly technological world. Everywhere cctv is installed. People should at least participate in a marathon for joy, ecstasy, fun, most importantly health. Forget who wins or not. Just enjoy that moment. I think every nation should promote marathon race at every level. That will enhance sporting spirit and health too.
