A city full of superheroes? Boulder, Colorado seems to be the place for the extremely physically fit, drawing those who love the outdoors to its 30,000 acres of unspoiled land, 200 miles of trails, and city-center paths and rivers. Of course, it’s in the foothills of the Rocky Mountains, a (Boulderian) stone’s throw from skiing and snowshoeing.
