Kelvin Kiptum training: How the world's fastest marathon runner trained!
Kelvin Kiptum, who sadly passed away far too early, set a new world record at the Chicago Marathon on October 8, 2023.
With a time of 2:00:35 hours, the Kenyan set the first marathon time under 2:01 hours. He took over from compatriot Eliud Kipchoge, who had previously broken the world record twice in a row.
