Dominic King is hoping tips from Mo Farah and Paula Radcliffe will help him achieve a personal best at London 2012.
The 29-year-old, who competes in the 50km walk on 11 August, was part of a recent training camp in the Pyrenees.
"It was was the first time I've experienced altitude training," the Colchester runner told BBC Look East.
"It was really good to learn from those guys about nutrition, psychology and just the general ethos of a professional athlete."
King has been racewalking since the age of 11 and he and twin brother, Daniel, are Britain's current number one and two.
There will be no family double in London, however, as Daniel failed to qualify for the Great Britain team.
"I feel like I'm doing this for both of us," said King.
"He is my training partner and my best friend. It would have been the cherry on the cake for my brother to have qualified as well but there's always four years' time in Rio and I'm very confident we can both get there."
King, who was disqualifed from the 20km walk at the 2002 Commonwealth Games but finished sixth four years later, is the first British walker to compete in an Olympic 50km event since Chris Maddocks in Sydney 12 years ago.
He has a personal best this year of four hours six minutes 34 seconds, but admitted: "I'm probably not going to get a medal - that's probably more for four, eight years' time.
"But I will be really happy if I go out there and finish the race with a personal best."
Despite his own disappointment, Daniel is delighted Dominic made the team and hopes it will spur them both on to greater things in the future.
"If he races to a good plan, I'm sure he can do very well.
"I'd be pleasantly surprised to see him finish high up in the field, but realistically top half would be a good performance," he said.
"I wish him all the best but I'm looking forward to getting back into sibling rivalry."
