Kenyan Eliud Kipchoge set a new marathon world record in Berlin on Sunday, smashing the previous best as he clocked 2hr 1min 39sec.
The 33-year-old Olympic champion, aided by a string of pacemakers through to 25km of the 42.195km race, took 1min 18sec off the previous best set four years ago by Dennis Kimetto.
It was the largest single improvement on the marathon world record since Derek Clayton improved the mark by 2:23 in 1967.
"My only words are 'Thank you!'," said Kipchoge, who sprinted into the lead after 100 metres and never let up.
"I was prepared to run my own race early so I wasn't surprised to be alone. I have trained so well for this race and have full trust in the programmes of my coach. I am just so incredibly happy to have finally run the world record as I never stopped having belief in myself."

"I'd said I was running my own race following my planning and I was confident."
