Kenyan athlete David Rudisha ruled out an attempt on his 800 metres world record at the London Olympics after comfortably winning his heat on Monday.
Rudisha, whose world record stands at one minute 41.01 seconds, is the overwhelming favourite to take the 800 title in London after missing out on selection for Beijing four years ago through injury.
“The track is fast. It looks good,” the 23-year-old world champion told reporters through a translator. “In this championship I don't look at the record. It is a medal that I want. Once I get the medal, toward the end of the season I can think about the record.”
Rudisha took the lead in his heat as the athletes broke from their lanes and gently increased his long, loping stride over the final lap for a straightforward victory in one minute 45.90 seconds.
The only man to have beaten Rudisha over 800 since 2009, Ethiopia's Mohamed Aman, also made Tuesday's semi-finals, winning a pedestrian race in 1:47.34.
