There are 12 medals up for grabs in the speed skating discipline; six for men and six for women. Skaters race along the 400m oval in two lanes and switch on each lap with the competitor on the outside lane moving in holding the right of way. In the team pursuit race, two teams of three skaters start at opposite sides of the track with the race completed when the last of the skaters crosses the finish line.
There are three events for men at the Olympics: the normal hill, the large hill and the team event. For the first time women will jump at the Olympics, but only on the normal hill. For the first time at an Olympics, new rules on compensating for wind conditions will apply, which mean athletes can be docked points for jumping in a wind the jury deems to be too favourable.
There will be 11 events at the Sochi Olympics, five for the men, five for the women and a mixed relay. The competitors race over a set distance and start at intervals of 30 seconds and have four shoots, the first and third in the prone position and the second and fourth standing. For every missed shot, a minute is added to the competitors' time.
There will be 12 gold medals up for grabs at the Sochi Olympics - six each for men and women in the individual, mass start, skiathlon, relay, sprint and sprint relay. Though there are different disciplines and different lengths of which the competitors compete on, essentially whoever finishes first wins.
Curling is played by two four-member teams, called rinks, on a sheet of ice 44.5 metres long and 4.75 metres wide. The aim is to deliver a polished stone, made of granite and with a handle on top, as close as possible to the centre of a series of concentric circles, known as the tee, and to knock away the stones of the opposing team at the same time.Team members sweep the ice in front of the stone as it glides, to keep the ice clean in the running path of the stone, speed it up or influence its direction.
The competition consists of four runs held over a two-day period. Medals are awarded based on the total time over the four runs, with the winner having the lowest overall time. If two teams complete the competition in a tie, they are awarded the same place.
There are only two gold medals to be won in skeleton. Each athlete completes a total of four runs with the winner having the lowest overall time. If two athletes complete the competition in a tie, they are awarded the same place.
Four gold medals are up for grabs. Individual competitions for men and women in the singles are held over two days with two runs per day. The four times are added together, and the fastest total time determines the winner.
