Skier / Snowboard Cross race. Teams of 4 compete for best Team time (total of fastest 3 times on course) and best individual times. Four racers on a team (may be skiers, boarders or both on a team) run at the same time (i.e. you are not on course at the same time as your opponent.)
There are two categories for teams: Platinum (all racers 50 years old or more) and Sport (all racers 19 years or older.) There are four individual categories: by gender (female/male) and sport (ski/snowboard.)
