No other runner could be seen in the distance when Kelvin Kiptum tore through the finish line tape in Chicago. Not only did the 23-year-old Kenyan win on Sunday, but he set a new world record.

Kiptum crossed the finish line at the Chicago Marathon with an unofficial time of 2 hours and 35 seconds. If confirmed, Kiptum will have beaten two-time Olympic champion Eliud Kipchoge's record, set at the 2022 Berlin Marathon, by 34 seconds.

It would also make Kiptum the first athlete in the world to break 2 hours and 1 minute in a record-eligible marathon.

"I knew I was coming for a course record, but a world record — I am so happy," Kiptum said, according to World Athletics. "A world record was not on my mind today, but I knew one day I would be a world record-holder."
