Tatyana Ivanovna Tomashova (born 1 July 1975 in Perm) is a former Russian distance runner.

Career

At the 2000 Summer Olympics, she competed in the 5000 metres but participated in shorter races thereafter, mainly in the 1500 metres. She is a double world champion and single Olympic silver medallist in this event. On 31 July 2008, Tomashova was suspended by the IAAF, along with six other Russian track and field athletes, for doping offences. She was charged under IAAF rules 32.2 (b) and 32.2 (e) for a "fraudulent substitution of urine which is both a prohibited method and also a form of tampering with the doping control process". She was set to compete in the 2008 Summer Olympics. On 20 October 2008, it was announced that Tomashova, along with six other Russian athletes would receive two-year doping bans for manipulating drug samples. She initially came fourth in the 1500 meters at the 2012 Summer Olympics. However, after doping offences by other athletes, she was promoted to the silver medal position. In September 2024, twelve years after the London Games, the Court of Arbitration for Sport announced that Tomashova herself had been stripped of her medal, and banned for ten years for further doping violations.

Personal bests

International competitions

On 3 September 2024, CAS banned Tomashova for 10 years as a doping penalty. In addition, all results recorded in competitions from June 21, 2012 to January 3, 2015, including the silver medal at the London 2012 Olympics in the women's 1500 metres, were invalidated. This is not Tomashova's first suspension, as she was suspended in 2008 on suspicion of tampering with doping samples. Tomashova is a 2004 Olympic silver medalist in the 1,500 meters, as well as a two-time world champion (2003 and 2005) in this discipline.
