Olympic sport this week
The week's highlights include British triathletes Alistair Brownlee and Helen Jenkins winning the latest leg of the World Championship series over the Olympic course, runner Mo Farah securing another impressive victory at the Diamond League meeting in Crystal Palace, and Richard Faulds shooting his way to European gold and silver.
Former world champions Alistair Brownlee and Helen Jenkins showcased their gold-medal potential for London 2012 by winning their respective races over the Olympic course in Hyde Park.
Their success in the fifth leg of the seven-stage World Championship series ensured the British pair met the selection criteria for the Olympics.
Brownlee, who had said the flat course would not suit his aggressive style, nonetheless broke free in the run to finish 25 seconds ahead of Russian Alexander Bryukhankov. Alistair's brother Jonathan also met the 2012 criteria by finishing third.
Jenkins clinched her first win in the World Championship series, finishing seven seconds clear of second-placed American Gwen Jorgensen. It was a third successive Hyde Park podium finish for Jenkins, who won the 2008 World Championships when it was still a one-off race.
Mo Farah reinforced his world-class credentials with a 10th consecutive victory of the year at the London Diamond League meeting. The 28-year-old sprinted the last 200m of his 3000m race in 25 seconds.
World record holder David Rudisha was another standout performer, running the fastest 800m on British soil. The Kenyan son of a Masai warrior crossed the line in 1min 42.91sec.
Grenada's 18-year-old Kirani James set a world-leading 44.61sec in the 400m to mark him out as the man to beat at the World Championships, especially with Jeremy Wariner missing through injury.
World champion Sanya Richards-Ross was an impressive winner in the women's equivalent race, in which a shocked Christine Ohuruogu finished last.
Britain's Jenny Meadows ran a season's best in the 800m, and compatriot Helen Clitheroe booked her World Championship place with a massive personal best over 5000m.
Hannah Mills and Saskia Clark battled tough conditions to retain the overall lead in the 470 class standings at the halfway stage of the Olympic test regatta in Weymouth and Portland.
Three-time Olympic champion Ben Ainslie is level on points with Frenchman Jonathan Lobert at the top of the Finn fleet despite capsizing at one point in wind conditions that reached 22 knots.
British Olympic champions Iain Percy and Andrew Simpson are outside the top 10 in the Star event after being forced to retire in the second race when their mast came down.
Former Olympic champion Richard Faulds confirmed his return to form after a lean 2010 by winning team gold and individual silver at the European Championships in Belgrade on Sunday.
The triumphant men's double trap team also comprised Stevan Walton and Peter Wilson, who was fourth in the individual event - won by Russian Vasily Mosin.
Another Briton, Michelle Smith, earned silver in the 50m rifle prone earlier in the week.
American Bradley Ellison made history at the foot of the Rocky Mountains by winning his third successive individual gold in a World Cup stage.
Ellison overcame Dmytro Hrachov of the Ukraine in the final at the third leg of the World Cup series, staged in Utah. He also won gold in the men's team and mixed team events.
The women's individual event was won by India's 16-year-old Commonwealth champion Deepika Kumari, who was also part of the women's team beaten by Ukraine in the final.
Great Britain's archers struggled to make an impression, with none of the men's or women's contingent managing more than one individual win each.
Great Britain claimed two silvers in the World Junior Championships at Eton Dorney Lake as the Olympic and Paralympic rowing venue was tested over the weekend.
The women's four were surprise second-place finishers ahead of New Zealand, while the men's eight overcame Germany to win silver. Germany dominated the event though, winning six golds and a total of 10 medals from 13 races.
GB Rowing's performance director David Tanner declared the 2012 test event a resounding success.
A global chemical giant has won the right to produce the £6m "wrap" around the main Olympic stadium. Dow will make 336 fabric panels, each 25 metres high and 2.5 metres wide to cover the outside of the stadium. Olympic officials had scrapped the "wrap" late last year to save money.
