The top 30 finishers from the Northeast region preliminary round take on an even more challenging course to lock a spot in the Vegas finals. Athletes must face three new Miami obstacles: the bungee bridge, jumping bars and the wall lift. But who has the best shot--costumed competitor Jamie Rahn, the 5'5 Michael Needham or world free running champ Tim Shieff? Or maybe the stuntman who lives in his van, Louis Moco, has the best shot at glory? See which fifteen from this episode make it to Sin City for the national finals.
