Mo Farah ran further in an hour than any human in history to claim the first world record of his dazzling career.
Farah was back on the track after three years away claiming he had missed the buzz of stadium competition whilst chasing marathon glory.
He marked his return by breaking the one-hour world record which Haile Gebrselassie had held for 13 years.
It was close run thing with the 37-year-old, who was pushed hard throughout by Bashir Abdi, beating the Ethiopian’s mark by just 45 metres to finish with a total of 21,330m.
But that didn’t matter to the Londoner, who was just relieved to finally have a world record to set alongside his 10 global gold medals.

Jo Coates insisted the decision to appoint the sport’s first black head coach was 100 per cent on merit.
“There are lots of people who are great coaches,” she said. “But this role is so much more than this. We want someone to fundamentally make the difference in this sport.
“He is our Pep and we will put all support that he needs around him.”
