As if to explain, he takes position atop a 10-foot wall enclosing a sculpture park in downtown Denver. With a running start, Ford lunges hands-first at a railing, vaulting himself backwards over the wall and deftly landing on the ground.
Not missing a beat, he springs forward, bounding over a concrete block and soaring 6 feet into the air, landing on the ledge of a wall, gripping it with the tips of his fingers and toes in what is known as most appropriately a cat leap.
Ford is a traceur. And he's practicing what's known in the French world as Parkour, or in English parlance, freerunning.
