Emmanuel Wanyonyi went close to breaking David Rudisha’s vaunted 800m world record in Thursday’s Diamond League meet here in what was a mixed night for Olympic champions making their return after the Paris Games. 

Wanyonyi repeated the blistering form that saw him win in the French capital, going within 0.20 seconds of the 1min 40.91sec world record set by Rudisha when winning Olympic gold in London in 2012.
