Armstrong admits doping

Washington - Lance Armstrong admitted for the first time late Thursday that he had used banned substances to enhance his cycling performances.

The American cyclist answered "yes," when asked by Oprah Winfrey, whether he had used EPO, human growth hormones, blood transfusions and other banned substances to achieve his seven Tour de France Titles.

"I view this situation as one big lie that I repeated many times,"he said.

He said it was impossible in his opinion to win the race without using illegal substances.//DPA
