We all have a duty to help protect the integrity of sport in the UK.
Elite athletes need to feel confident they are competing against clean athletes, just as those entering competitive sport need to believe their role models have achieved their success cleanly.
If you notice any suspicious behaviour that gives you concern, please contact Report Doping in Sport, a confidential and anonymous 24-hour phone line. Call 0800 032 2332.
Alternatively, you can submit information via a secure and confidential online form .
