Merritt faces health challenge after C'ships

BEIJING - Olympic champion and high hurdles world record holder Aries Merritt will have a kidney transplant next week, after competing in the Athletics World Championships in Beijing, the 30-year-old American said on Wednesday.

Merritt, who was told that he would never run again after being diagnosed with kidney disease in 2013, set the second-fastest time behind compatriot David Oliver in the heats of the 110m hurdles on Wednesday.

The disease, caused by a rare genetic disorder found predominantly in African-Americans, has damaged his organs to such an extent that he will receive one of his sister's kidneys in Arizona on Sept 1.

"I'm here for mental sanity more than anything," he told reporters.

"I don't want to be sitting in my house awaiting surgery, I'd rather be out enjoying life to the fullest.

"Who knows? This could potentially be my last championship if things don't go well. But I'm optimistic that I'll be back and able to train for the Rio Olympics."

Merritt had a brilliant 2012, winning gold at the London Olympics and shattering the world record with a time of 12.80sec at the Brussels Diamond League meet the following month.

It was after he finished sixth at the 2013 World Championships that his illness was diagnosed.

"When they told me I'd never run again, my whole world ended in my mind," he added.

"That I am here again running shows me that I'm a fighter and that I can overcome anything if I stay with a positive mind.

"For this championships, I'm going to take it one race at a time."

He ran 13.08sec in last night's semi-finals to emerge as the top qualifier for today's final, and said he was glad to have the news about the transplant out in the open.

"Just to be keeping that secret, it felt like a weight had been lifted when I was able to share it," he said. "The positive outreach has been amazing. I love running, I love competing, this is my life and here I am."
