A slew of international publications has reacted to Eliud Kipchoge's record in Vienna as the first human being to run a marathon under 2 hours.
Leading that charge of coverage was the Guardian newspaper that broke the news.
"Eliud Kipchoge made history in Vienna by running the first-ever sub-two-hour marathon in a time of 1hr 59min 40sec. Cheered on by thousands of fans, the Kenyan world record holder and Olympic champion completed four laps of a 9.4km circuit around the Prater, a park in the centre of the Austrian capital, " the Guardian newspaper wrote.
The British Broadcasting Corporation (BBC) was not left behind in weighing in on Kipchoge's sub two marathon run.
It reported that the Kenyan marathoner's record would not be officially recognised as a world record.
"Kipchoge has become the first athlete to run a marathon in under two hours, beating the mark by 20 seconds. The Kenyan, 34, covered the 26.2 miles (42.2km) in one hour 59 minutes 40 seconds in the Ineos 1:59 Challenge in Vienna, Austria on Saturday."
"It will not be recognised as the official marathon world record because it was not in open competition and he used a team of rotating pacemakers, " the BBC wrote.
The Cable News Network (CNN) reported that Kipchoge had first tried to crack the sub 2 marathon run in Italy under the sponsorship of Nike but failed.
This time around, he was being supported by INEOS, a petrochemical chemical, CNN reported.
"Kipchoge's first crack of going sub-two-hour in Monza, Italy, was part of Nike's Breaking2 project. This time he was being backed by petrochemical company Ineos in an attempt called the 1:59 Challenge."
"Despite the achievement, the milestone won't count as a world record. In fact, Ineos hasn't even submitted a request to the IAAF for the attempt to be officially ratified," CNN wrote.
