PIX: Gold medal winners on Day 11 of the London Games

Dutchman Dorian van Rijsselberghe became the Olympic men's RS:X windsurfing champion on Tuesday, the final time the event will be held at the Games.

Britain's 2004 bronze medallist Nick Dempsey took silver in front of a cheering home crowd including his twice Olympic gold medallist wife Sarah Ayton and their son on the Nothe shoreline medal course.

Poland's veteran Olympic board campaigner Przemyslaw Miarczynski won bronze in his battle with Germany's Toni Wilhelm.

This was the last Olympic men's race on the RS:X board following an International Sailing Federation decision in May 2012.

Kiteboarding will replace windsurfing at the 2016 Rio de Janeiro Games.

Dutch officials have said that Van Rijsselberghe will leave for California straight away to take up kiteboarding.

Spaniard Marina Alabau Neira won the Olympic RS:X windsurfing women's gold medal on Tuesday.

It was Spain's first gold of the Games.

Britain's Laura Trott claimed her second gold of the Olympics with victory in the women's track cycling omnium on Tuesday, pipping Sarah Hammer of the United States to the title in a thrilling time-trial finale.

Hammer and Trott had been on level points at the end of the first day, with the 20-year-old Briton leading the overall standings thanks to her flying lap win.

But the American edged ahead with a scorching pursuit victory on Tuesday, before finishing a place ahead of Trott in the 10 kilometer scratch race to widen her overall lead to two points with only the time-trial to go.

Trott's win in the 500m time trial put her one point ahead of the American to snatch the gold.

Australia's Annette Edmondson, who won the scratch race, took the bronze.

Since triathlon joined the Olympics in 2000 it has produced seven out of seven upset wins but Alistair Brownlee bucked the trend in spectacular style on Tuesday when he delivered a perfectly-executed race plan to claim Britain's first medal in the sport.

Their second came moments later when younger brother Jonathan took bronze, despite having to serve a 15-second penalty for mounting his bike too early, while Spaniard Javier Gomez, fourth four years ago when he was top-ranked, split them with silver.

The three men, who race together for French team EC Sartrouville, dragged themselves from the blue carpeted floor to hug each other as each of them achieved a memory to cherish.

Feng Zhe showed off his mastery of the parallel bars and then wagged the now familiar index finger to confirm his top dog status as he seized the Olympic gold medal for China on Tuesday.

Feng produced a solid swinging exhibition incorporating a number of impressive somersaults, twists and handstands to earn 15.966 as all of his main rivals fluffed their routines.

So confident was Feng about his performance, he quipped: "I wanted the gold, I felt the judges were under more pressure than me."

Brothers Kazuhito and Yusuke Tanaka had raised the possibility of completing a Japanese one-two after earning the top two qualifying scores but both wobbled and wavered across the bars on Tuesday and left empty handed after finishing fourth and eighth respectively.

Feng, the 2010 world champion, surpassed Germany's Marcel Nguyen by 0.166 of a point while Frenchman Hamilton Sabot picked up a surprise bronze.

Feng's success gave the Chinese men's gymnastics team their third gold of the London Games.

Deng wins beam gold medal

Meanwhile another Chinese, Deng Linlin, beat her compatriot Sui Lu, the world champion, to the Olympic balance beam title on the final day of artistic gymnastics.

Deng, herself world champion on the apparatus in 2009, gave China their fourth gymnastics gold medal of the Games, an hour after Feng Zhe had won the parallel bars title.

Sui, competing first, pulled off a difficult routine but cried on her coach's shoulder after Deng surpassed her by 0.1 points with a score of 15.600 at the North Greenwich Arena.

Aly Raisman snatched the bronze medal from 2004 champion Catalina Ponor of Romania on a tiebreak after the judges increased the difficulty element of her score following a review requested by the United States team, upping her final mark.

Dutchman Epke Zonderland showed off a flamboyant gravity-defying routine to snatch the Olympics horizontal bar title on Tuesday.

Zou Kai had been the favourite to win the gold medal as China had won every Olympic and world title on the apparatus since 2008 but he was easily surpassed by a flying Dutchman who showed no fear as he pulled off three back-to-back release manoeuvres to whip the crowd into a frenzy.

Zonderland triumphed with 16.533 points and German showman Fabian Hambuchen, who thought he had bagged the title with his high-flying performance, had to make do with silver on 16.400.

Zou, the 2008 champion who had been hoping to give China a third gymnastics gold on Tuesday following successes on the parallel bars and balance beam, took the bronze. 

World champions Russia lived up to predictions they would cement their dominance of synchronized swimming at the London Games, claiming the title for duets on Tuesday with a crisp routine inspired by horror movies and macabre fairytales.

Natalia Ishchenko and Svetlana Romashina - in costumes decorated with dolls, their eyes framed by toy-like eyelashes - took gold after scoring 98.9 points out of a possible 100 in the free routine executed for the final.

That marked an improvement on Monday's score for the same sequence and took their total points to 197.1 - more than four points clear of their nearest rivals Spain.

Russians, bringing a tradition of ballet to the pool, have taken home the Olympic gold for duets since Sydney in 2000, earning a reputation for seamless execution in a sport that demands precision and endurance - paired with a smile.

Spain's tango-inspired routine helped their duo to silver, retaining the same medal position as in Beijing four years ago. China ame 0.03 points behind with their dragon choreography as they took bronze.
