ALPINE

Alpine snowboarding was one of the original Olympic events in 1998. In World Cup competitions, there are several formats including parallel giant slalom and parallel slalom. The Olympics features only parallel giant slalom.

In parallel giant slalom, or PGS, riders race head to head on side-by-side giant slalom courses with the winner advancing to the next round. Parallel slalom, or PSL, is similar but with athletes competing on slalom courses.
