Nike Oregon Project coach Alberto Salazer and former Oregon track and field star distance runner Galen Rupp have been accused of violating doping rules, according to BBC and ProPublica investigations.
The claim says that Salazar and American record holder Rupp broke the anti-doping rules in an incident back in 2002.
Both Salazar and Rupp are denying the claims. Rupp has never failed a drug test, and Salazar told the BBC and ProPublica that he follows all doping rules.
Several athletes have stepped forward and aided the investigation, citing how Salazar would push for the use of illegal substances. Runner Kara Goucher, who left the Oregon project seven years ago, is among the group coming forward.
“He is sort of a win-at-all-costs person and it’s hurting the sport,” Goucher told ProPublica.
Steve Magness, who coached with Salazar in 2011, has also stepped forward. Magness said he saw a document showing Rupp’s blood levels, and that it  indicated he was on testosterone medication.
“When I saw that, I kind of jumped backwards,” Magness said in the BBC report. “Testosterone is obviously banned — everybody knew that.”
Salazar is a legend in the running world, having made a name for himself by winning the New York Marathon three years in a row. He currently has a large group of professional runners that he trains on the Nike Oregon Project, including Rupp and Great Britain’s Mo Farah. The investigation didn’t find evidence that Farah broke any rules.
