• Nike Oregon investigation may seek blood and urine samples• Ukad says it will not respond to ‘trawling expedition’
The
UK Anti-Doping Agency has said it will not hand over Sir Mo Farah’s blood and urine samples to any investigation into the Nike Oregon Project unless it is given credible evidence to suggest they might contain a banned substance.
The World Anti-Doping Agency is expected to re-test some samples of athletes from the training group, where Farah ran between 2010 to 2017, as part of a new investigation into the Oregon Project that was announced in the wake of Alberto Salazar’s four-year ban for doping offences. The US Anti-Doping Agency, which led the initial investigation into Salazar, had also previously expressed an interest in getting hold of Farah’s samples held in the UK – a move resisted by Ukad.
