Cambridgeshire triathlete Will Clarke says he is in the best form of his career, a year before London 2012.
The 25-year-old is currently second in the World Championship Series, in front of Great Britain team-mates Alistair and Jonathan Brownlee.
And he can enhance his Olympic aspirations with a top-three finish at August's London leg of the series.
"I feel in the form of my life at the moment," the former Under-23 World Champion told BBC Radio Cambridgeshire.
"I'm in Lanzarote at the minute training hard for the Olympic qualifying event in London. Hopefully I can hold my form and have a good race there as well.
"I'm aiming to do two really hard weeks to give my fitness a boost."
Clarke's only previous Olympic appearance was in Beijing in 2008, where he finished 14th, a performance he claimed was one of the lowest moments of his career.
"If you go to the Olympics for Great Britain then you're kind of expected to be challenging for the medals because you're one of the strongest nations in the world," he said.
"If you get anything outside the top three it's considered a failure."
This time around, Clarke is fighting a battle just to be in the squad.
There could be three places available for the GB men's triathlon team, if they can finish as one of the top six countries in the World Series.
And with the Brownlee brothers expected to take two spaces, only one spot remains vacant.
Recent debate has been between sending a genuine medal contender, such as Clarke, or a cycling pacemaker to assist the top contender to ensure a medal.
But Clarke is confident a medal at the upcoming event in Hyde Park would secure his status as a genuine medal contender.
"As far as I'm concerned if you're one of the top three British athletes in the build-up to the Olympics and you're consistently up there then you should go," he said.
Will Clarke is one of BBC Radio Cambridgeshire's three featured athletes as part of 'Olympic Dreams' in the build-up to London 2012.
