(CNN) - The U.S. Anti-Doping Agency says it will release Wednesday more than 1,000 pages of evidence detailing the involvement of cyclist Lance Armstrong in what the agency calls "the most sophisticated, professionalized and successful doping program that sport has ever seen."
Armstrong, who won an unprecedented seven Tour de France titles, announced in August that he would no longer fight doping charges that the USADA brought against him earlier in the year. The famed cyclist's decision prompted the USADA to ban the 40-year-old athlete from competition and strip him of his wins dating to 1998, though there were questions of whether the organization had the authority to take such action.
The USADA filed doping charges against Armstrong in June. Armstrong retired from professional cycling in February 2011, though he continued to compete in triathlon events.
The USADA, a quasi-government agency recognized as the official anti-doping agency for Olympic, Pan American and Paralympic sports in the United States, accused Armstrong of using, possessing, trafficking and giving to others performance-enhancing drugs, as well as covering up doping violations.
Armstrong's attorney blasted the accusations as "wrong" and "baseless," much like Armstrong has vehemently denied other such claims in the past.
