There are 232 athletes. Russia hosted the 2014 Winter Olympics in Sochi from February 7 to February 23, 2014. Russia, as host, competed in all 15 sports with a team of 232 competitors. It is Russia's most extensive Winter Olympics squad to date. The country has been plagued by doping scandals that have cost some of its top athletes their medals. More than 100 Russian athletes were banned from various events for systematic drug cheating. However, President Vladimir Putin called for an "anti-doping culture" in Russian sport and said those caught using drugs would be punished. He also said the country was making progress in cleaning up sport. Russia started taking part in the Olympic movement in 1952 when it sent a small team to Helsinki. Since then, it has taken part in every Summer Olympics but one (1972 Munich), while it has participated in every Winter Olympics except one (1968 Grenoble). Sochi was once again chosen to host the Games after being awarded the project in 2005. The city staged the Winter Olympics four years ago and became Russia's most popular winter destination. Around 20 million people visited the city during the competition. Sochi has been criticized for poor planning and construction delays that saw some venues close days before they were due to open.
