Miller is the biggest star in skiing

The American had previously said he was considering skipping the Games due to pressure from sponsorship obligations, media duties and fans' attention.

"I'm going to race as of now and I've made some progress as far as deciding why and how I'm going to try and make it a positive thing," he said.

Miller revealed his change of heart on on the eve of the new World Cup season.

He will compete in the men's giant slalom in Soelden in Austria this weekend, after becoming the first American man in 22 years to win the overall title last season.

"I came out of the season really feeling pretty negative about the whole (Olypmics) situation and the way I knew I'd be lumped in with other athletes," he explained.

It's about the struggle being the most important thing, as opposed to the triumph at the end Miller on the Olympics

"In the US, they have a really result-oriented 'Get as many golds as you can' attitude and 'We have to get more golds than any other country' (philosophy).

"It's a really unhealthy attitude toward the Olympics and sport in general. It was really irritating for me to know I would be at the forefront of that whole advertising plan in the US.

"It was too much of a false representation and too much of a strain on my belief about sport and about the Olympics."

A contract with sportswear giant Nike changed his attitude.

"We'll be doing some pretty cool and unique positive commercials," he added.

"That was a big step because I needed a forum besides (the media) where I could feel I was making contact with the public and at least getting my ideas out there that although gold medals are great, the Olympics and the Olympic message are still as clear as ever.

"It's about the struggle being the most important thing, as opposed to the triumph at the end or the gold."

Miller 'surprised EPO is illegal

Miller courted controversy last week when he said he was surprised that erythropoietin (EPO) is illegal.

But he reiterated on Thursday his belief that current anti-doping policies do nothing to protect the health of athletes.

"I feel it's super hypocritical for a drug to be legal for you to buy, but not for an athlete to buy," he said.

"Used in a way directed by a doctor or directed by the research that's out there, even some drugs like EPO could potentially balance the risk of long-term health problems against the potential gains for not injuring yourself.

"When I look at all these professional athletes when they are 45 or 50, they have knees that don't work at all, shoulders that don't work, back problems.

"I think that's a much more common occurrence than a guy who is 40 or 50 who has serious problems because of some steroid he was taking when he was 20."

Miller said he has never used performance-enhancing drugs.

"I don't even use any creatine or vitamins or supplements or anything," he added.

"The point is that I don't think it's a really big deal. I think people should be able to do what they want to do."
