MOSCOW (AP):Mo Farah of Britain finished another championship with a long-distance double. The 5,000-10,000 metres gold medallist from the London Olympics again proved there is no match for his finish after a long race, kicking for home to win the 5,000 after a first gold on the opening day of the IAAF World Championships in Moscow.
Over an exhilarating last lap, Farah held off Hagos Gebrhiwet of Ethiopia and Isiah Koech to make him the defining long distance runner of his age.
In the men's shot put, favourite Ryan Whiting, the season's top performer, took silver with a toss of 21.57 metres, losing out to David Storl of Germany, who retained his title with a throw of 21.73m.
And despite a big tradition in the long jump, the United States failed to medal. Aleksandr Menkov of Russia won, beating Ignisious Gaisah of the Netherlands with a world-leading effort.
Russia got off to a great start when Olympic hammer throw champion Tatyana Lysenko set a world championship record to retain her title, edging 2009 gold medallist Anita Wlodarczyk of Poland.
In a seesaw competition, Lysenko finally got the upper hand with a throw of 78.80 metres on her fourth attempt, edging Wlodarczyk by a mere 34cm.
In the gold medal standings, both the United States and Russia had five gold going into the closing weekend, but the Americans had 16 overall, compared to 11 for the host nation.
Off the track, pole vault great Yelena Isinbayeva backed off from her comments criticising homosexuality. The Russian said she "may have been misunderstood" when she condemned homosexuality and criticised Swedish high jumper Emma Green Tregaro for painting her fingernails in the rainbow colours to express support for gays and lesbians.
"English is not my first language," Isinbayeva said. "Let me state in the strongest terms that I am opposed to any discrimination against gay people."
