VeloNews is reporting today that the U.S. Anti-Doping Agency is about to release the names of "15 to 25 masters, elite and pro cyclists" who have been notified of violations because they allegedly conspired with a former pro cyclist, Joe Papp. The article explains that Papp pleaded guilty earlier this year to distributing HGH and EPO to 187 customers, including cyclists, and implies that Papp entered a plea arrangement and may be providing information on his customer list in order to obtain leniency.
Relatedly, last week, we learned in several news reports that a 41 year old amateur racer, Duane Dickey, was given a lifetime ban for refusing to submit to a doping test. Dickey was found to fail a test years earlier and his refusal this year constituted his second violation. Apparently, Dickey was one of Papp's clients and Papp is now leading the authorities to other clients. Interestingly, Dickey was not a very successful amateur but still was found doping. This suggests doping in cycling may be among the amateur ranks.
The article also says that Papp indicated on Twitter that a pro cyclist in the top 5 at one of the stages in the Tour of Utah this year was doping. The top five at that stage included: Levi Leipheimer, Francisco Mancebo, Ian Boswell, Darren Lill and Phil Zajicek. Levi Leipheimer was also named in the Lance Armstrong investigation when Floyd Landis made his claims earlier this year.
