Kenyan David Rudisha broke the 800m world record for the second time in a week, setting a new marker of 1min 41.01sec at a meeting in Rieti, Italy on Sunday. It was only last Sunday in Berlin that the 21-year-old had set a mark of 1:41.09 to beat Wilson Kipketer's 13-year-old record by two hundreths of a second.
At Rieti last year the 2006 world junior champion set an African record as he exploded onto the scene in senior middle distance running. Although he only reached the semi-finals at the 2009 World Championships, he continued to improve resulting in his eventually beating the record set by Kipketer. Having done so, Rudisha had said he could go faster as it was his first attempt to break the record.
