In case you have not seen it yet, the RT “debate”: http://www.runnersworld.com/races/wading-mud?cm_mmc=Twitter-_-RunningTimes-_-Content-Racing-_-MudRaces
I side with Beverly, of course. I must recognize that, despite RT's noted editorial cant, there must be a vested interest in the angle that Chase mentions: bringing more people 'from the couch to running' with mud runs and their ilk allegedly serving as a gateway. Growing the sport benefits sponsors and thus benefits lifestyle periodicals. That seems like the only reason the counterpoint from Chase — who seemingly represents anything but the traditional in running — would be included.
