ROME (AFP) 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 Kipketers 13-year-old record by two hundredths of a second. I just knew I was in good shape. The conditions were perfect. I expected to break two records in seven days, said Rudisha. It was the eighth world record broken in the history of the venue. I have always received a very warm welcome in Rieti. I love this track and the Rieti crowd who have always given their support. This record is for them. Asked on which part of the race he needs to improve to further lower his record in the future, Rudisha said: I cannot say now what I need to improve. I will see in training with my coach what I can improve but I think I need to change only small details. 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.
