The current mens marathon world record is 2:01:25, set by Kelvin Kiptum of Kenya at the London Marathon on April 23, 2023. This time is recognized as the official world record by World Athletics, the international governing body for the sport of athletics. Kiptum beat the previous record of 2:01:39, set by Eliud Kipchoge of Kenya at the Berlin Marathon on September 26, 2022. It is worth noting that Kipchoge has run a marathon faster than Kiptum at the 2019 Ineos 1:59 Challenge where he set a time of 1:59:40, but this run does not count as a legal world record due to the conditions of the race.
