Doping scandal rocks athletics

 Athletics suffered one of its darkest days following revelations this week that two of the world's fastest men, Tyson Gay and Asafa Powell were among six athletes to have tested positive for banned substances.

Gay and Powell both aged 30, and Jamaican woman sprinter Sherone Simpson who was part of the gold medal-winning quartet at the Athens Games and a silver medallist at the London Games last year were found to have an illegal product in their systems in an out-of-competition drug test in May.

Drugs have provided the world of athletics with a fierce opponent ever since the emergence of systematic forms of doping in the former Eastern Europe, with Kenya being one of the places where the news reverberated like a booming echo.
