Former Olympic champion Asbel Kiprop faces a four-year ban

Former Olympic Champion Asbel Kiprop could face a four-year ban following official confirmation that he tested positive for a banned blood-booster.

The Athletics Integrity Unit (AIU) confirmed media speculations that the 28-year-old three-time world champion had failed a doping test.

Kiprop alleged that testers extorted money from him, an allegation the AIU did not address. He also claimed that the testers might have interfered with his sample.

The AIU, which was set up to combat all forms of corruption and ethical misconduct within athletics, was satisfied there was no interference with his sample.

They however maintained that Kiprop had been given advance notice that he would be tested.

The case is now with an International Association of Athletics Federations’ disciplinary tribunal.

Kiprop is among almost 50 athletes from the east African nation, long revered for its distance running pedigree, who have failed doping tests.

The most famous being former Boston Marathon champion Rita Jeptoo and Jemimah Sumgong, Olympics marathon gold medalist in Rio de Janeiro in 2016.
