Luge consists of four events at the Olympics: men's singles, women's singles, doubles and team relay. Team relay is an Olympic event for the first time this year.
Participants lie on the small sled in a supine position, which means they are on their backs, looking up, with their feet first as they race down the course.
The sled has two runners that are controlled by the competitor's legs, enabling the racer to steer. Racers can obtain speeds in excess of 80 miles per hour.
Unlike the bobsled or skeleton, luge competitors begin the race seated on the sled and push themselves with their hands at the start.
Each singles competitor completes four runs down the course, with the cumulative times of the four heats determining the order of finish and medal awards.
In the doubles event, two competitors from the same country race on one luge, and the order of finish is determined by the cumulative time over two runs.
The team relay consists of a women’s singles luger, a men’s singles luger and a doubles team, all from the same country, and the three race consecutively over the course. The order of finish is based on the combined times of the three racers.
Competition is held on the 20-turn course at the Sliding Center Sanki, which is located in Rzhanaya Polyana, Russia, which is about 37 miles from Sochi.
