My son, who's done Boston a few times, commented snidely:
Yeah, this is sort of old news, that's making a revival as part of the
build up to the Boston Marathon on Monday. What's happening is that
untrained people are 'doing' a marathon in 5 or 6 hours, which isn't
even fast enough to break a sweat, but they're still drinking four or
five cups of gatorade at each water table. This isn't an issue for
people who treat it as an athletic event, rather than an ambulatory buffet.
