Kelvin Kiptum is the fastest marathoner of all time. He broke the world record in 2023 in Chicago with the time of 2:00:35.
Nobody has ever finished under 2:00:00. I don’t know how, but experts estimated that based on the rates of how people have gotten stronger and faster over time, it might happen in 2070. But if anyone could speed up that timeline, it would’ve been Kiptum. He only debuted in 2022, running a 2:01 in Valenica, and at only 24 years old, he could reasonably break his own record.
Sadly, he was killed in a car accident about this time last year. The Nairobi City Marathon this year was dedicated to his legacy.
