Eliud Kipchoge skirted a fine line between recklessness and genius as he smashed his own marathon world record by 30 seconds with yet another extraordinary display in Berlin.
The double Olympic champion looked as serene as it is possible to be after 26.2 miles of hard toil, crossing the line in 2hr 1min 9sec to surpass his best set four years ago. For good measure, the 37-year-old Kenyan also beat the second-placed Mark Korir by nearly five minutes.
