Mo Farah parts ways with Salazar

London: British long-distance running star Mo Farah will no longer work with long-time coach Alberto Salazar but has denied the split is related to doping allegations surrounding the Oregon-based guru, it was reported on Monday.

In an interview with The Sun, Farah, the four-time Olympic champion over 10,000m and 5,000m, said he was ending his association with Salazar because of a move back to Britain.

The 34-year-old Somalia-born star began training with Salazar in 2011 at his Oregon Project camp in Portland, and won his first world title the same year in the 5,000m at the Daegu World Championships.

Salazar's training base however has been the subject of intense scrutiny from the United States Anti-Doping Agency. A leaked USADA report this year asserted that Salazar had likely violated drug protocols, later denied by the coach.

Farah, who has repeatedly denied involvement in doping, told The Sun the allegations involving Salazar were not behind his decision. "I'm not leaving the Nike Oregon Project and Alberto Salazar because of the doping allegations," he told the paper. "This situation has been going on for over two years, if I was going to leave because of that I would have done,” he said.
