It's like the giant parallel slalom we all know and love, just on a shorter course.

What to watch for: The 40-second hill has tighter turns, so the hard cutting around each gate chews up the course quickly, giving the sport a less graceful, wild rodeo feel. "This is more head to head, racing man to man," says 32-year-old U.S. contender Justin Reiter. "It's like the F1 of snowboarding."
