Cheats have cost me medals - Jo Pavey

European 10,000m champion Jo Pavey says she has lost medals to athletes who have later been proven to have cheated.

Pavey was speaking to the BBC in response to allegations that top coach Alberto Salazar violated anti-doping rules.

Among the allegations outlined in a BBC investigation, it is claimed Salazar was involved in doping the American long distance runner Galen Rupp.

Salazar and Rupp both strenuously deny any wrongdoing.
