Spain surprise Aussies to snatch gold
Tamara Echegoyen-skippered Spain surprised favourites Australia to win gold in the women's match racing class - the last sailing medal of London 2012.
Having overcome Ekaterina Skudina's Russia in the semi-finals on Friday, the Iberians went on to deny the Australian crew a fourth sailing gold medal of the Games.
Australia twice recovered from going behind in the best-of-five series, but Echegoyen, Sofia Toro and Angela Pumariega went onto ensure Spain top the podium.
Russia's Sergey Kirdyapkin won the gold medal in the 50-kilometre walk in an Olympic record time. The former world champion finished in three hours, 35 minutes and 59 seconds, almost a minute clear of Australia's Jared Tallent, who took silver for the second Games in succession, with China's Si Tianfeng claiming bronze.
New Zealander Lisa Carrington won gold in the women's 200m kayak sprint in a time of 44.638 seconds at Eton Dorney. The silver medal went to the Ukrainian Inna Osypenko-Radomska, while the Hungarian Natasa Douchev Janics took bronze.
In the men's 200m canoe sprint final, Ukrainian Yuri Cheban took the gold in a time of 42.291 seconds, ahead of Lithuanian Jevgenij Shuklin in second and Russia's Ivan Shtyl, who took bronze.
Russia also secured gold in the men's K2 200m sprint after Yury Postrigay, 23, and 22-year-old Alexander Dyachenko led from start to finish, crossing the line 0.7seconds faster than Belarusians Raman Piatrushenka and Vadzim Makhneu, who claimed silver, and Britain's Liam Heath and Jon Schofield in third.
Evgeniya Kanaeva became the first rhythmic gymnast to defend an Olympic title after the Russian won gold with a series of breathtaking performances in the individual all-round final at Wembley arena.
Kanaeva was in a class of her own as she scored 116.900 to retain her title, ahead of fellow Russian Daria Dmitrieva (114.500) in silver with Liubou Charkashyna of Belarus (111.700) taking bronze.
