What do traditional track & field and the X Games have in common? At first glance, not much at all. But dig a little deeper, and you will find the X Games event "Step Up Moto X." Added to the X Games in 2000, the event involves motocross riders launching themselves up a dirt ramp to see who can clear a bar raised progressively higher and higher overhead. While the propulsion system involved in soaring over the bar differs from that of track and field's pole vaulting, the two sports share a similar philosophy - to go as high as you possibly can.
