Kenya's David Rudisha tonight lit up the Olympic Stadium with a sensational victory in the 800m, breaking his own world record in the process.
As Chairman of the London Organising Committee of the Olympic and Paralympic Games (LOCOG) and former Olympic 800m silver medallist Sebastian Coe looked on, Rudisha made the most of ideal conditions, storming through the first lap in 49.28 and powering to the gold medal in 1:40.91.
