LAST WEEK'S HIGHLIGHTS
Silver for GB's world triathlon champion Helen Jenkins in Sydney; Beijing silver medallist David Florence leads GB's 2012 canoe slalom team; below-par Paula Radcliffe struggles in Vienna; Tom Daley earns a place on the podium again.
Britain's Helen Jenkins finished second in the opening round of the World Triathlon Series in Sydney.
The reigning world champion was beaten by Australia's Erin Densham, who won with a time of 2hr 1min 29sec.
William Clarke was the top British finisher in the men's race, coming in eighth, 38 seconds behind winner Steffen Justus of Germany.
Great Britain's triathlon world champion Alistair Brownlee and his brother Jonny did not participate in the men's event.
Beijing 2008 silver medallist David Florence will lead a British team of five slalom canoeists at London 2012.
Florence, 29, won two of the best-of-three selection races in the men's C1 (one-man canoe) category on the Olympic course at Lee Valley.
He has also earned a place in the two-man C2 boat alongside Richard Hounslow.
Hounslow beat Athens silver medallist Campbell Walsh to selection in the K1 one-man kayak, with Lizzie Neave winning the place in the women's K1.
Ed McKeever, Jon Schofield and Liam Heath will paddle for Team GB at London 2012 after winning races at the British sprint canoe squad's national regatta.
McKeever will race in the men's K1 (one-man kayak) 200m event, with Heath and Schofield in the two-man discipline over the same distance.
The three world silver medallists are the first sprint racers to be selected.
Meanwhile, Beijing 2008 Olympic champion Tim Brabants beat rival Paul Wycherley in the first of three race-offs.
Haile Gebrselassie beat a below-par Paula Radcliffe in Sunday's head-to-head half marathon in Vienna.
The Briton had targeted a time below 70 minutes in the "Emperor versus the Queen" race but ended with a time of 1 hour 12 min 03sec, more than 11 minutes behind the Ethiopian.
"I am at a loss to explain why it was quite so bad. I still would have expected and hoped for a time in the 69s," she told BBC Radio 5 live.
Asked if she was worried about her Olympic chances, she added: "I'm not giving up on it by any means."
Tom Daley continued his recent revival with a third successive World Series silver medal in the 10 metre platform in Moscow.
The 17-year-old produced a gritty rather than spectacular display in the absence of China's world champion Qiu Bo, his 520.95 points putting him behind Lin Yue of China.
Daley had earlier finished a disappointing fifth in the 10m platform synchronised competition alongside Peter Waterfield.
Olympic test event bronze medallists Tonia Couch and Sarah Barrow were sixth in the women's 10m synchronised competition.
Smith, 17, totalled 208kg, beating her personal best by four kilograms, but narrowly missed out on a podium finish.
"I'm over the moon to have smashed the 'A' standard," said Smith, who was just three kilograms short of bronze and seven away from winner Boyanka Kostova.
Alison Williamson remains on course for a sixth successive appearance at the Olympic Games after progressing to this week's third and final British selection shoot.
The Athens 2004 bronze medallist currently lies in third place behind leader Naomi Folkard and Amy Oliver, with three Olympic places available. Charlotte Burgess completes the women's finalists having just pipped Nicky Hunt by 20 points.
Larry Godfrey, Simon Terry, Alan Wills and Michael Peart will battle for the three places in the men's event.
Elsewhere, the individual events at the first World Cup meeting of the year in Shanghai were won by defending champions Brady Ellison and Ki Bo Bae.
