I disagree that CrossFit doesn't train you for a marathon. It might not train you to be an elite marathoner but it does train you to be an adequate one. Greg Admundsen who is a fairly well known Crossfitter did nothing by main page workouts for preparation for a 100 mile race and he finished 80 miles. There is solid data, described in the article and found elsewhere on the web that short, intense fitness sessions where most of your work anaerobically will in fact prepare you for aerobic activities. CrossFit is the empirical proof of that.
