Jacob Kiplimo was on world record pace for about 22 miles at the Chicago Marathon.
Jacob Kiplimo of Uganda won the Chicago Marathon after being under world record pace for about 22 miles, while Conner Mantz finished fourth with the fastest time ever run by an American.
Kiplimo clocked an unofficial 2 hours, 2 minutes, 23 seconds. He was under world record pace until about the 22nd mile, then lost two minutes in the last four-plus miles.
The world record of 2:00:35 was set by the late Kenyan Kelvin Kiptum at the 2023 Chicago Marathon.
Kiplimo, who was running his second career marathon after accolades on the track and in the half marathon, is now the seventh-fastest marathoner in history.
Mantz clocked an unofficial 2:04:43, breaking the American record in the marathon of 2:05:38 set by Khalid Khannouchi at the 2002 London Marathon, which was the world record at the time.
Mantz's time also bettered Ryan Hall's 2:04:58 from the 2011 Boston Marathon, but Boston times are ineligible for record purposes as the course is point-to-point and net downhill.
Mantz ran 2:05:08 at this past April's Boston Marathon. He has been the top American men's finisher at his last six marathons, including winning the 2024 Olympic Trials and placing eighth at the Paris Games.
The next major marathon is New York City on Nov. 2, featuring Olympic gold medalists Kipchoge and Sifan Hassan of the Netherlands in their debuts in the five-borough race.
