LONDON // Alistair Brownlee delivered another impressive run for a crushing victory in the London leg of triathlon's world series Sunday to stoke up expectation he can repeat the feat when next year's Olympic race is run over the same Hyde Park course.

Britain's Brownlee, the 2010 world champion, controlled the race to finish in 1 hr 50.09 mins 9 secs.

Russia's Alexander Bryukhankov was second, 25 seconds back, and Brownlee's younger brother, Jonathan, was third after overhauling Javier Gomez, the current world champion.

The victory completed a great weekend for British triathlon after Helen Jenkins won Saturday's women's race.

Subject to rubber-stamping by the British Triathlon Federation, she and both Brownlees are now sure of their places at London 2012, where they will seek to win the country's first medals in the sport.

With the London race in its third year on partly the same course, which goes out of the Royal Park to take in landmarks such as Buckingham Palace and the Wellington Arch, it was always likely to be one of the most straightforward test events for London 2012.

Race organisers and Olympic officials were delighted with the large crowds and action-packed racing, which was also tested by traditional British summer conditions of snatches of sunshine interspersed with downpours.

Fears that algae growth would cause problems for the 1,500-metre Serpentine swim also proved unfounded, and Gomez and Jan Frodeno, the Olympic champion of Germany, led the 65-man field out of the water.

Brownlee was right behind them and it did not take long for the 23 year old to stamp his authority on the race as he led a four-man breakaway a lap into the seven-lap cycling leg and never looked back.
