Better off in the pub
Runners banned from using personal stereos at events like the London Marathon? How absolutely insane. I know for me I would be incapable of running without some tunes to keep me going. And I fail to see where the danger lies - surely a controlled environment like the Marathon is as safe as a personal stereo user will ever get.
