Retired British sprinter Roger Black has spoken out in favour of new anti-doping rules after he suffered a defeat at the hands of drug cheats.
The double World Championship gold medallist explained to Daybreak how American sprinters robbed him and his teammates of "the moment" of victory.
"What they took away was the moment. We never experienced the moment. The moment where you're standing on the rostrum with three other teammates and celebrating to be the best in the world."
