We've featured tons and tons of extreme videos shot on GoPro Cameras. Usually what makes them exciting is experiencing first hand views of activities you probably won't participate in yourself. This video has gone viral since it was released yesterday and for good reason. Mountain biker Evan Van Der Spuy probably didn't see this huge Red Hartebees (an Antelope from southern Africa) charging him as he raced the Albert Falls Dam. Luckily his friend Travis Walker had his GoPro camera rolling and captured this remarkable footage.
