10 of the best/craziest runs in America

We picked five great American cities and selected one run that defines the awesomeness that is these United States for each. But because this isn’t “Runner’s World,” we amped up the action with two twists of our own…

One, each city gets a totally bonkers race (featuring costumes, DJs, and/or lasers) to go with its more majestic counterpart. Two, we recruited the help of McDavid -- makers of awesome protective sports apparel -- to lockdown two expert trainers willing to share their knowledge on how to keep your body intact, whether you’re pounding pavement or neck deep in foam because, yes, there will be foam.
