No Doping Evidence Against Farah - Officials

Officials have found "no evidence of impropriety" by Mo Farah as they investigated allegations against his coach Alberto Salazar.

Britain's track and field body launched a probe after Mr Salazar, Farah's American long-distance running coach, was accused of encouraging athletes at the Nike Oregon Project to dodge anti-doping rules.

But British Athletics found "no reason to question the appropriateness of the input given by the Oregon Project to Mo Farah's training regime".

The allegations were made by Mr Salazar's former assistant Steve Magness and former runner Kara Goucher in a story by US investigative website ProPublica.

Mr Salazar has rejected the claims, saying he "will never permit doping".

Farah has denied ever using any banned substance, saying: "I'm 100% clean" .

Farah was questioned by the United States Anti-Doping Agency in a routine meeting at a London hotel at the weekend, after a winning return to the Olympic Stadium for the Anniversary Games.

The double Olympic gold medal-winning star is currently training at his base in Font Romeu in the Pyrenees, and is preparing to defend his 5,000 and 10,000 metres titles in Beijing.

The 32-year-old is hoping to become the first man to complete the long-distance double at two World Championships.
