Ep 12. Knockout Punch

With two legs to go, the pressure's on to snag one of the few remaining wins. At the insertion flag, teams must design and build handmade rafts durable enough to survive the roughest whitewater they've faced yet. Endurance is derailed after a crash leaves them struggling . The Alaskans need a win, but when their rafts flip, they must sprint to the finish. The Military team trails Endurance by one point, and can't afford to make any mistakes.
