London Marathon organizers say a British court has ordered Russian marathon runner Liliya Shobukhova to repay prize and appearance money after being banned for doping.

The High Court judgment mandates Shobukhova to repay 377,961.62 pounds ($498,000) plus costs relating to her 2010 marathon victory and second-place finish the following year in the British capital.

London Marathon chief executive Nick Bitel says "the next step is to get the judgment enforced in Russia. It will be a long and difficult process but we will pursue it as we are determined that cheats should not benefit."

Shobukhova was stripped of her 2009-2011 results when the Russian federation initially banned her for two years for blood doping, and she was ordered to forfeit her prize money.

The IAAF appealed for a four-year ban from the Court of Arbitration for Sport. A settlement was reached in June for Shobukhova to serve a three-year, two-month ban through March 2016.
