Olga Danilova

Olga Valeryevna Danilova, born on 10 June 1970 in Bugulma in the Tatar Autonomous Soviet Socialist Republic, is a Russian cross-country skier who competed from 1991 until she was banned for using performance-enhancing drugs in 2002. She won eleven medals at the FIS Nordic World Ski Championships, including four golds in the 4 x 5 km relay in 1995, 1997, 1999 and 2001. At the 1998 Winter Olympics in Nagano she won gold in the 15 km classical and in the relay, and silver in the combined pursuit. Her 2002 Olympic medals were later removed after blood tests showed darbepoetin, following a Court of Arbitration for Sport ruling, and the International Ski Federation gave her a two-year ban.
