LONDON – British distance running star Mo Farah has refuted suspicions that his startling form is down to drugs, saying that it was solely hard work that got him atop the podiums at the London Olympics and Moscow worlds. "I work hard at what I do," Farah told the Daily Telegraph from his altitude training base. "If I didn't I wouldn't be up here in the mountains, spending more than six months a year away from my wife and kids. That's why it hurts." Farah backed up his 5,000-10,000m double at the London Games with a similar feat at last month's world championships in the Russian capital to ensure his place among the top distance runners there have ever been. But he has had to battle back against allegations that his streak to podium-topping form was down to doping. –AFP
