Shobukhova won the 2010 edition of the race before she was given a 38-month suspension from the sport after her biological passport showed "abnormal haematological curves".

Along with a two-year suspension, she was also stripped of her win at the 2010 London Marathon and victories at the Chicago Marathon in 2009, 2010 and 2011.

The London Marathon then launched legal action in an attempt to recoup some of the money given to Shobukhova and the British High Court has today ruled in their favour.

The Court has instructed the now 38-year-old to return a total of £377,961.62 ($497,851.05/€450,023.48), her prize and appearance money from the 2010 and 2011 races, plus costs.

Obstacles still remain for London Marathon Events, however, as the judgement now needs to be enforced in Russia.

London Marathon Events chief executive Nick Bitel has confirmed they will look to redistribute the money to athletes which “Shobukhova cheated out of their rightful dues”.

Under a new scheme, the winners of this year’s London Marathon, Kenyans Jemima Sumgong and Eliud Kipchoge, will have to wait five years to receive their full prize money after a new payment plan was introduced to deter drugs cheats.

“It will be a long and difficult process but we will pursue it as we are determined that cheats should not benefit,” he said.

“Any money we get back will be redistributed to the athletes that Shobukhova cheated out of their rightful dues.

“We are determined to make marathon running a safe haven from doping.

“We will continue to do everything we can to ensure cheats are caught and do not benefit from cheating.”

Shobukhova announced in May that she would not attempt a comeback in the sport after he ban ended, instead focusing on a career in coaching.

In December 2014 it had been reported that she had paid $550,000 (£380,000/€500,000) to cover up positive doping results.

Shobukhova had her ban extended to three years and two months by the International Association of Athletics Federations (IAAF) but the World Anti-Doping Agency granted her a reduction of seven months.

It followed her providing information to the Independent Commission chaired by Canadian lawyer Richard Pound which led to Russia being banned by the IAAF from international competition.

Before her results were erased following her positive drugs test, Shobukhova's personal best of 2 hours 18min 20sec made her the second fastest female marathon runner in history behind Britain's Paula Radcliffe.
