The races, including the people who put it on, don't give a rip how many people break 2:30, 4:40 or even three hours. All they care about is boosting the number of entrants. Wat they hell does anyone expect? It's Disney, for buck's sake.
And for those who care, the race itself is suck, with many long, boring stretches on access roads, exit ramps, a hard-as-hell divided highway offering no shade, and cobblestones. It's bad enough being out there for even three hours, I can't imagine five or more.
All the clowns who stage this blight on marathoning are concerned about is that enough first-timers with nothing to use as a measuring stick come away crowing about what a great event it was, with costumed characters doing their cute little shuck-and-jives at the aid station and a Mickey medal at the finish. As is typical in this country, masterful marketing of complete dogshit.
