Triathlete Stuart Hayes will run the supporting 'domestique' role to leading British contenders Alistair and Jonny Brownlee at London 2012.
He has tasted success in his own right previously, with his most notable victory coming in the Kitzbuhel triathlon two years ago.
The Twickenham-native missed out on selection to the Athens Olympics in 2004, but finished that year ranked third in the world.
