Armstrong: Three-year absence
Lance Armstrong believes his return to racing can be a success after his performance at the Tour Down Under.
"It's given me reassurance that I can still do this."

The seven-time Tour de France winner finished 29th overall and was often seen attacking out of the peloton during a race not suited to his strengths.
"It's given me reassurance that I can still do this," Armstrong said.
"You don't know, you've been out for three and a half years, the body can deteriorate and gets older and it reassures me that I worked hard, I've done the right work and I think I can still race at the highest level."
Changed
The Texan has also used his comeback as an opportunity to put right the poor relationships he had with some people within the sport.
"I can look at my career, I can look at my relationship with the press, I can look at my relationship with the fans, I can look at my relationship with the peloton and I can reassess those," he added.
"I've changed some things."
Armstrong also had some flattering words for overall Tour Down Under winner Allan Davis.
"He was seemingly invincible in one or two stages and controlled the race very well, he never panicked, he raced like a true pro," the American said.

Australia's Allan Davis won the 2009 Tour Down Under professional road cycling race.
Sprint specialist Davis completed Sunday's final stage in the main pack to maintain the lead he had built up in time bonuses from sprint wins earlier in the race.

122 cyclists completed the six day race around a circuit starting and ending at Adelaide, South Australia.

American cyclist Lance Armstrong also participated in the race, his first professional bike race since the 2005 Tour de France. It is not clear if the seven-time Tour de France winner intended to compete for the general classification, but he did make an unsuccessful breakaway on Sunday in pursuit of a stage victory. Despite several attacks over the week, Armstrong placed 29th in the general classification.
