The 2014 Winter Olympics in Sochi.
The 2014 Winter Olympics, officially known as the 22 Olympic Winter Games, were a major international multi-sport event held in Sochi, Russia, in the tradition of the Winter Olympic Games.
It is the first Olympics in Russia since the breakup of the Soviet Union in 1991. The Soviet Union was the host nation for the 1980 Summer Olympics in Moscow. A total of 98 events in 15 winter sport disciplines were held during the Games. A number of new competitions were held during the Games, including biathlon mixed relay, women’s ski jumping,
mixed-team figure skating, half-pipe skiing, ski and snowboard slopestyle, and snowboard
parallel slalom.
In preparation, organizers focused on modernizing the telecommunications, electric power, and
transportation infrastructures of the region. The budget of the Games was over US$51 billion.
With an average February temperature of 8.3°C and a humid subtropical climate, Sochi is the
warmest city to host a Winter Olympic Games.
Mascots
For the first time in Olympic history, a public vote was held to decide the mascots for the 2014
Winter Olympics. The official mascots were a polar bear, a snow hare, and a snow leopard.
Opening ceremony
The opening ceremony took place on February 7, 2014. More than 3,000 people from artistic
groups participated in dance, ballet, acrobatic and circus performances during the opening
ceremony which was watched by a 40,000 strong audience at Sochi’s Fisht Olympic Stadium.
Figure skater Irina Rodnina and ice hockey player Vladislav Tretiak lit the torch.
Participating National Olympic Committees
A record 88 nations qualified to compete. Seven nations—Dominica, Malta, Paraguay, TimorLeste, Togo, Tonga, and Zimbabwe—are making their Winter Olympics debut.
Sports
98 events over 15 disciplines in 7 sports were included in the 2014 Winter Olympics.
Medals
Sochi’s medal design resembled Sochi’s landscape. Those who won gold medals on 15 February
received special medals with fragments of the Chelyabinsk meteor, marking the one-year
anniversary of the event where pieces of the cosmic body fell into the Chebarkul Lake in the
Ural Mountains in central Russia.
