Fyshwick banker Craig Miller gets lost in a sea of suits and home loans when he's in the office, but the unassuming man in Lycra will swap credit cards for an Olympic Games dream next week.Miller has spent $15,000 on his Olympic ambition and packed up his desk on Friday for a two-week mission in Rio.This is the story of New Zealand-born wrestler Miller, a failed drug test that revived his Olympic dream and the twists and turns that led him to a Canberra bank before setting his sights on Rio.The 31-year-old Greco-Roman specialist will be one of the last athletes to arrive at the Olympic village when he makes a mad dash around the world to make his Games debut.Miller was told just two weeks ago he would be competing at the Olympics after Australian rival Vinod Kumar returned a positive test for an anabolic agent and a stimulant that led to him being banned for four years.Miller fears that some of his rivals in Rio will be cheating the system as the Games get swept away in the Russian drug controversy.But Kumar's absence has opened the door for Miller to fill the Africa-Oceania qualifying spot for New Zealand in the 66 kilogram event. The only problem was he had exhausted all of his leave during the qualifying process and had to ask his Westpac boss for extra time to chase his dream."But [boss Jo Percy] was more excited than me ... she was asking if she could tell people but it wasn't public yet," Miller beamed."I don't think she'd try and stop me, she knows how much this means to me and how big it is.  
She's fully behind me."I'm working right up until when I leave. I spent about $15,000 trying to qualify for the Olympics, so money's a bit tight."There's no sponsorship or high performance funding or anything like that. I've still got a mortgage and the bills to pay. I'm not funded, so it's all off my own back."Fyshwick is the last place you'd expect to find a budding Olympian just days before the Games.Most athletes have spent the past month in training camps around the world, using altitude chambers and technology to boost their medal chances.Miller has been behind his desk checking home loan requests and opening accounts for customers.He moved to Canberra after finishing seventh at the 2014 Commonwealth Games for his wife to start a job at Dickson College and to train in the capital.But his Olympic hopes appeared dead when he was knocked out of the Africa-Oceania qualifiers and Kumar won the Rio spot for Australia.Miller returned to his desk job but three months later Kumar was suspended for four years for using a banned substance."I do feel cheated, because had I won back in   April, I would have had more time to prepare," Miller said.???"We suspected [he was using drugs]. I saw him at the national champs wrestling in the 74 kilogram [division] and he was pudgy. Then he went to the Canberra Cup three months after and he had veins popping out of his chest."I used to be 105 kilograms, I'm wrestling at 66 kilograms now, so I've got a lot of loose skin. I'm not bulging muscle because I've always got that loose skin layer, and he had none of that."It made me sceptical ... but you don't go public about that sort of stuff unless you have proof."Miller still fears some of his competitors at Rio may be drug cheats."There's 19 [athletes] in my weight [division] and I wouldn't know how many of them are doping, but there will be at least one," he said. "I felt vindicated when it did come out, but it is disappointing because you like to think everyone's on a level playing field."If you lose it should be your fault and not someone who's cheating you out of it. I felt cheated. "I try not to dwell on it too much, because it's not a good place to be mentally - you want to be positive and more internally focused - but I can't change any of that now."Miller will rub shoulders with some of the biggest names in world sport when he arrives in Rio.But for the past few weeks he's been juggling a 40-hour per week job with 25 hours of training at a humble Canberra gym."No one's going to expect me to do well, there's no real pressure on me apart from the pressure I'm putting on myself," he said."A few seconds of brilliance is the difference between winning and losing. I just have to do one throw and pin them."Miller will compete in the 66-kilogram division of the Greco-Roman wrestling on   August 16.
