The film, entitled "Britain’s Olympic Ambition for 2012: On a golden journey", features Olympic hopefuls 16-year-old judo player Ben Fletcher and 17-year-old fencer Sophie Williams.

The film was commissioned in response to BOA research which suggests the majority of British medal winners already have Olympic Games experience.

Research conducted by the BOA over the last five Olympic Games has demonstrated that, on average, nearly 70 per cent of Britain's gold medals were won by athletes who were competing in at least their second Olympic Games.

In total, 55 per cent of Britain's medals won since 1992 were brought home by athletes who had attended one or more Olympic Games prior to winning their first gold, silver or bronze medal.

The BOA created a unique pilot programme ahead of the Beijing 2008 Olympics entitled "Britain’s Olympic Ambition 2012" to help break down barriers, boost psychological preparations and confidence and dispel mystique around the Olympic Games.

The ultimate aim of the programme being to ensure that a much greater level of non-Olympians achieve success at their first Olympic Games in London.

Fletcher and Williams, who are part of Lloyds TSB Local Heroes scheme, were filmed as part of the 150-strong "Britain’s Olympic Ambition 2012" group of London 2012 prospects that travelled to Beijing last August to experience the Olympic Games.

The film is being distributed to aspiring athletes by the governing bodies of all winter and summer Olympic sports as part of their preparation for future Games.

The film will also be sent to SportsAid athletes and Lloyds TSB Local Heroes, 250 Olympic hopefuls supported by the London 2012 sponsor each year, as part of their ongoing sporting journey.

It is hoped that by watching the film, young athletes will be able to gain more insight into the size and scale of an Olympic Games. In turn, this should enable them to be better prepared and less overwhelmed during what is often a daunting and distracting experience.

Andy Hunt, the BOA’s chief executive, said: "The programme’s aim was to provide sports specific event exposure and to replicate, as closely as possible, an athlete’s overall Olympic experience as we have research showing that around 70 per cent of gold medallists at any Olympic Games have attended previous Olympic Games before medalling.

"'Britain’s Olympic Ambition 2012’ and the ‘Britain’s Olympic Ambition for 2012: On a golden journey’ film will help give young hopefuls an added boost that can help them reach their full potential at London 2012 regardless of whether they have firsthand experience of previous Olympic Games or not.

"We believe this experience will contribute towards the BOA’s aim of finishing fourth in the overall medal table in 2012.”

Sally Hancock, Lloyds TSB head of London 2012 sponsorship said: “Lloyds TSB is committed to taking London 2012 to all four corners of the country and to supporting young emerging talent across the regions.

"The filmmakers of ‘Britain’s Olympic Ambition for 2012: On a golden journey’ had behind the scenes access at the Beijing Games and we hope that the film will provide London 2012 prospects with a unique insight into what they can expect in four years time.”

Rachel Cawthorn, a canoe flatwater paddler who was also part of the programme, said: “The trip to Beijing was an invaluable experience that I'll never forget.

"It was useful to see the day to day stuff that the athletes have to deal with, such as the athlete Village, the travel between venues, media interest and the dining room.

"All aspects which make the Olympics exceptional.

"Having experienced these possible distractions first hand in Beijing will certainly help me to deal with them in 2012. "This trip has reinforced my goal of competing at 2012, and has left me with memories which will help me through the hard training times.”

Mhairi Spence, who was one of the athletes from modern pentathlon on the programme said: “The Olympic Games are absolutely massive, but going there and experiencing it for myself made it seem much more real and less scary.

"It made me realise that if you keep your focus, it’s nothing out of the ordinary and like the other competitions we do.

"Going to the Games was such an amazing experience and it makes anyone even more motivated to want to compete at an Olympics.”

Denise Lewis, the 2000 Olympic heptathlon gold medallist, was one of the mentors for the programme in Beijing, along with rowers Ed Coode and Alison Mowbray.

She said: “I became involved in this programme because of my own Olympic experience.

"I remember what it was like for my first Olympics - I was completely terrified and quite overwhelmed by the whole situation.

"It’s important that you almost demystify the Olympic Games for a lot of athletes.

"In some ways you need to treat it as just another competition.

"If you can give them the confidence and allow them to see what it’s like so they are not completely blown away by the experience then hopefully they’ll do their best and be the best prepared athletes going into the London 2012 Games.”
