British distance runner Mo Farah says he is “100% clean”, following doping allegations against his coach Alberto Salazar.
UK Anti-Doping (Ukad) and the US Anti-Doping Agency (Usada) are investigating claims made in the BBC Panorama programme Catch Me If You Can that Salazar violated various anti-doping rules and used testosterone medication on a 16-year-old Galen Rupp in 2002.
Both men deny all the claims and there is no suggestion Farah has been involved in any doping.
