The quest to break the two-hour marathon barrier has captivated runners and fans for decades. In 2019, Eliud Kipchoge ran 1:59:40 in the INEOS 1:59 Challenge in Vienna, but this time was not ratified as an official world record due to controlled conditions, including pacers and a tailored course.
The official men's marathon world record is 2:00:35, set by Kelvin Kiptum at the 2023 Chicago Marathon. Kiptum's record is recognized by World Athletics. The women's world record is 2:09:56, set by Ruth Chepngetich at the 2024 Chicago Marathon.
Experts debate when a sub-two-hour marathon might be achieved in a race setting. Some predict it could happen within the next decade, while others note the significant physiological and environmental challenges. Advances in training, nutrition, and shoe technology continue to push the boundaries.
