David Rudisha became the first athlete to set a new world record on the track at London 2012 as he won 800m gold at the Olympic Stadium.

The 23-year-old Kenyan stormed his debut Olympic final to become the first man inside one minute 41 seconds, clocking 1:40.91.

Botswana’s Nijel Amos took silver, with fellow teenager Timothy Kitum in third.

British runner Andrew Osagie was in eighth place but still clocked a personal best of 1:43.77.

Reigning world champion Rudisha led from the off, setting an opening lap of 49.28 seconds, and stormed further clear down the back straight.

With the rest of the field dragged along by his pace, only Abukaker Kaki in seventh failed to record a personal best.

In 18-year-old Amos and Kitum, 17, the future of the event looks in good hands but whether anyone can get near the dominant Rudisha before the next Games in Rio looks unlikely.

Rudisha has set the three fastest 800m times of all time and made them look easy.

His pace was consistent throughout, clocking 23 seconds for the first 200m, 25 for the second, 25 for the third, and 26.1 for the final quarter.
