Live coverage from Hyde Park in London as the world's best triathletes compete in the latest stage of the World Championship Series.

Held on 2012's Olympic course, it is a chance for the likes of Britain's in-form brothers Alistair and Jonathan Brownlee to demonstrate their big 2012 medal potential. The priority though is the 2011 World Championship title, which is currently held by 2010's London triathlon winner, Javier Gomez of Spain.

The women's race promises to be just as competitive, with Britain's Helen Jenkins looking to add to the world title she won three years ago.
