In recognizing Kenyan Geoffrey Mutai's mark of 2:03:02 at the 2011 Boston Marathon as (at the time) "the fastest Marathon ever run", the IAAF said: "Due to the elevation drop and point-to-point measurements of the Boston course, performances are not eligible for World record consideration." "The decrease in elevation between the start and finish shall not exceed an average of one in a thousand, i.e."The start and finish points of a course, measured along a theoretical straight line between them, shall not be further apart than 50% of the race distance.".He broke the two-hour barrier in Vienna in 2019 when he ran 1:59:40 in a race that did not conform to regulations.ĭefending champion Guye Adola and Ethiopian compatriot Andamlak Belihu managed to keep pace, initially, but Adola dropped back a few meters as Kipchoge was clocking kilometer-splits of between 2:47 and 2:50.See also: List of world records in athletics § Criteriaįor a performance to be ratified as a world record by World Athletics, the marathon course on which the performance occurred must be 42.195 km (26.219 mi) long, measured in a defined manner using the calibrated bicycle method (the distance in kilometers being the official distance, the distance in miles is an approximation) and meet other criteria that rule out artificially fast times produced on courses aided by downhill slope or tailwind.
Kipchoge set off at a furious pace on Sunday, covering the first 10 kilometers in just 28:23 and clocking 42:32 at the 15k-mark, hinting at a sub two-hour attempt.
