Anchor leg: The fourth and final leg of a relay race.
Classical technique: The traditional ski racing technique. Both skis stay parallel to each other. At 2010 Vancouver Games, the classical technique will be used in four events (30km/15km pursuit, individual sprint, 4x10km/4x5km relay, 50km/30km mass start)
Freestyle technique: The skating ski racing technique. Developed in the 1970s, it closely resembles the motions of ice skating, pushing the inside edge of the ski simultaneously backward and outward at about a 45° angle. It is usually faster than classical technique. At the 2010 Vancouver Games, the freestyle technique will be used in four events (15km/10km interval start, 30km/15km pursuit, team sprint, 4x10km/4x5km relay)
Glide wax: Wax used to decrease the friction between the skis and the snow. It is applied to the entire ski in freestyle races, but only to the front and rear tips of the skis in classical races. The temperature and texture of the snow dictates what kind of wax will be applied on race day.
Individual start: Also called interval start, where racers start skiing at even intervals, not at the same time. Instead of racing against each other, they race against the clock.
Kick wax: Also know as grip wax, it increases the friction between the skis and snow in order to improve traction. It is applied to the middle third of the skis for classical races. The temperature and texture of the snow dictates what kind of wax will be applied on race day.
Mass start: Racers start simultaneously at the sound of the gun. Instead of racing against the clock, they race against each other. The winner is the first one to cross the finish line.
Piste: The snow-covered track or course that is used for racing.
Pit stop: Designated area where racers change from classical skis to freestyle skis in the pursuit event.
Pursuit: Since 2006, the race format of the pursuit has changed. Instead of having a staggered start based on a time in a previous race (as in biathlon), the race is conducted as a mass start with the first half of the race done in the classical technique and the second half in the freestyle technique. At the midway point, racers change from classical skis to freestyle skis in a designated area called the pit stop.
Scramble leg: The first leg of a relay race. Named this way because relay races feature mass starts with all the skiers bunched together.
Speed trap: A section of the course a coach will set to guage ideal skis and wax before a race.
Vertical: An uphill climb
Wax technician: Called a wax tech for short, a staff member responsible for finding the ideal glide and/or kick wax for a given race and snow temperature.
