Olympic champion and 800m world record-holder David Rudisha has confirmed that he will compete in Lausanne on July 9, the ninth stop for the IAAF Diamond League meeting.
This will be Rudisha's fourth appearance at the meet, having run there in 2007, 2010 and 2011. He will face stiff opposition from world champion Mohammed Aman of Ethiopia, the man he intends to reclaim his world title from in Beijing in August.
