CNN — Cyclist Lance Armstrong was involved in "the most sophisticated, professionalized and successful doping program that sport has ever seen," the U.S. Anti-Doping Agency said Wednesday in preparing to release more than 1,000 pages of evidence in the case.
The evidence involving the U.S. Postal Service-sponsored cycling team includes "direct documentary evidence including financial payments, emails, scientific data and laboratory test results that further prove the use, possession and distribution of performance enhancing drugs by Lance Armstrong," the agency said in statement.
In August, four days after a federal judge dismissed Armstrong's lawsuit seeking to block the agency's investigation, the seven-time Tour de France winner announced he would no longer fight the accusations. The agency then announced it would ban Armstrong from the sport for life and strip him of his titles dating back to 1998.
"The USPS Team doping conspiracy was professionally designed to groom and pressure athletes to use dangerous drugs, to evade detection, to ensure its secrecy and ultimately gain an unfair competitive advantage through superior doping practices," the agency said.
The scope of evidence against the team, including testimony from 11 team members who came forward to testify about their own involvement, is "overwhelming," the agency said.
Armstrong has consistently denied doping accusations. Neither he nor his manager, Mark Higgins, immediately returned telephone calls Wednesday seeking comment.
Between 1999 and 2005, won seven consecutive Tour de France titles, despite persistent accusations that he had used performance-enhancing drugs.
In February, the U.S. Justice Department closed a criminal investigation into illegal drug use by Armstrong without filing charges. The Anti-Doping agency filed its own case, which does not carry criminal penalties, in June.
