Mr Andrew, who had been training since September by daily riding a 10km course, was banned by national penny-farthing championship's organiser, the Oamaru Ordinary Cycle Club, from competing in any of the events on Saturday.
He says a "load of other reasons" were given, but the main one was that he had "the smell of alcohol on his breath".
He admitted to having a "few beers" at the Criterion Hotel on Friday night, but not enough to be drunk.
And the 28-year-old said a breath-test conducted on the morning of the racing showed he was below the youth (under 20 years) limit of 150mcgs.
The adult limit is 400mcg.
Yesterday, club captain, David Wilson, said it was "a difficult decision" to stop Mr Andrew from racing and the only official comment he would make was: "The club's board met prior to the racing and deemed Noel Andrew was unfit to compete".
Mr Wilson said that, at this stage, he did not want to comment further.
Mr Andrew started riding penny-farthings after he watched the first ever national championships in Oamaru in 1994.
He first competed in 1995, and has not missed a single championship until he was barred on Saturday.
"My whole year revolves around the penny-farthings [event], then I was told I was not allowed to race and not given a valid reason," he said.
Over the years, he has won consistently and said he was the only rider who had his name on every trophy.
He won the national championship in 2007, and since then it has been won by Christchurch riders.
This year, he had hoped to bring it back to Oamaru, and started training for the event.
He arrived at the club's rooms on Wansbeck St about 8.30am on Saturday to register for the races and collect his number.
"I never got the chance. I was trespassed from the building and physically removed," he said.
