By Gene CherryDOHA, Qatar (Reuters) – American Alberto Salazar, who has coached some of the world’s top distance runners including British multiple Olympic and world champion Mo Farah, has been banned for four years for doping violations.The U.S. Anti-Doping Agency (USADA) said Salazar’s punishment was for “orchestrating and facilitating prohibited doping conduct” as head coach of the Nike Oregon Project (NOP), a camp designed primarily to develop U.S. endurance athletes.The 61-year-old was quickly stripped of his accreditation for the world athletics championships in Doha at the request of the U.S. track and field federation, the sport’s governing IAAF said in a statement. Salazar said he would appeal USADA’s decision, and sportswear giant Nike said in a statement that it would stand by him.“I am shocked by the outcome today,” Salazar said in a statement. “My athletes and I have endured unjust, unethical and highly damaging treatment from USADA.” “The Oregon Project has never and will never permit doping. I will appeal and look forward to this unfair and protracted process reaching the conclusion I know to be true. I will not be commenting further at this time.”Yesterday, Farah said he was relieved that the investigation was over. “I have no tolerance for anyone who breaks the rules or crosses a line,” he said. UK athletics said in a statement that its own investigation in 2015, which cleared Farah to work with Salazar, was “restricted to the interaction of the Nike Oregon Project with Mo Farah and not an anti-doping investigation.”Salazar stopped coaching Farah in 2017 when the runner decided to move back to England. Farah said at the time that the doping investigation was not the reason they parted ways.USADA said that Salazar, who also coached American Olympian Matthew Centrowitz among other top distance runners, trafficked banned performance-enhancing substance testosterone to multiple athletes. Salazar also tampered or attempted to tamper with NOP athletes’ doping control process, the agency said after concluding its four-year investigation.Jeffrey Brown, who worked as a paid consultant endocrinologist for NOP on performance enhancement and served as a physician for numerous athletes in the training programme, also received a four-year ban. REACTION IN DOHASeveral members of NOP are competing in the world championships, including newly-crowned 10 000m champion Sifan Hassan.“I am shocked to receive the news of today’s ruling, especially during this time in which I am fully preparing for my next race in the world championships in Doha,” the Dutch runner said in a statement.“I like to state that this investigation is focussed on the period before I joined the Oregon Project and therefore has no relation to me. I was aware of the ongoing investigations when I joined the team and have always had a clean conscience, knowing we are being monitored to the absolute fullest by USADA and WADA.”None of the athletes Salazar has worked with was mentioned in Monday’s report.“The athletes in these cases found the courage to speak out and ultimately exposed the truth,” Travis Tygart, USADA chief executive officer, said in a statement. “While acting in connection with the Nike Oregon Project, Mr Salazar and Dr Brown demonstrated that winning was more important than the health and wellbeing of the athletes they were sworn to protect.”Salazar said that Tygart’s comment was misleading and he had never put winning above the athletes’ safety.This is completely false and contrary to the findings of the arbitrators, who even wrote about the care I took in complying with the World Anti-Doping code,” he said.Nike, which funds NOP, the nation’s most elite long-distance running training centre in Portland under a $460 million, 26-year sponsorship deal with US Track and Field, said it would support Salazar’s appeal“Today’s decision had nothing to do with administering banned substances to any Oregon Project athlete. As the panel noted, they were struck by the amount of care Alberto took to ensure he was complying with the World Anti-Doping code,” it said. “Nike does not condone the use of banned substances in any manner.” Salazar was a celebrated distance runner, winning three consecutive New York City marathons starting in 1980.
