Kenyan Eliud Kipchoge has created history after running a marathon under two hours in the Ineos 1:59 Challenge in Vienna on Saturday morning.
Kipchoge finished the 42.2km course in one hour, 59 minutes and 40 seconds to become the first person in history to complete a marathon sub two hours.
The effort will not be counted as an official world record due to the assisted conditions which included 41 pacesetters.
Kipchoge ran four laps of the 9.4km course at Prater in Vienna, with the pacesetters alternating in teams of seven.
The pacesetters were aided by lasers on the road from a support vehicle in front, exemplifying the manufactured settings.
The history-making effort comes after Kipchoge failed in his first attempt by 26 seconds in Italy in 2017.
“I am feeling good,” Kipchoge said.
“It has taken 65 years for a human to make history in sport. After Roger Bannister [ran a sub four-minute mile in 1954] it took another 65 years.
“I’m happy to be the man to run under two hours. No human is limited, and I’m expecting more people to do it after today.
“The 41 pacemakers are among the best athletes in the whole world.
“I want to say thank you, thank you for doing the job. We made history together.”
Kipchoge, who won Olympic gold in Rio 2016, holds the official current world record of 2:01:39 set at the Berlin Marathon last year.
