I'm surprised this hasn't been posted yet:
Apparently there is a big debate about it over on the crossfit forums because some guy posted "Yeah, but what's his Fran time??" and then another guy started talking about how if you did crossfit you would be better off than Magnusson because it is unhealthy to be that strong, and Benni is going to die young, etc etc.
Nevermind that he is basically at the top of his sport and achieved something never done before.
It was nice to see plenty of people standing up for Benni though, maybe that whole stereotype of crossfitters all being holier than thou geeks who think nothing is as good as crossfit isn't true after all.
