Hurdles world record-holder, Amusan, charged with anti-doping violation

“I intend to fight this charge and will have my case decided by a tribunal of 3 arbitrators before the start of next month’s World Championships,” she said.

“I am a CLEAN ATHLETE, and I am regularly; (maybe more than the usual) tested by the AIU – I was tested within days of my third ‘missed test.’ I have FAITH that this will be resolved in my favour and that I will be competing at the World Championships in August.”

On Sunday, Amusan took part in the Silesia Diamond League competition in Poland, where she set a new meeting record of 12.34sec.

At the Golden Spike athletics meet in the Czech Republic last month, she finished in third place in the women’s 100m hurdles, losing to reigning Olympic champion Jasmine Camacho-Quinn of Puerto Rico, who claimed victory in 12.42sec.

When asked by reporters about improving her world record pace, she said: “Nothing is impossible and 11 seconds? Most definitely”.

But she was less confident about an ongoing debate on raising hurdles to give priority to technique over speed.

“Don’t do that, don’t raise the hurdles. Please,” said Amusan, who is 5’1 (156 centimetres) tall.
