chicago marathon results: Chicago Marathon results: Jacob Kiplimo wins 2025 Chicago Marathon-Conner Mantz breaks American marathon record-Here’s the full result
How did Conner Mantz break the American Marathon Record?
Conner Mantz made history Sunday morning by breaking the two-decade-old American Marathon Record with a time of 2:04:43 at the 2025 Chicago Marathon. The 28-year-old American ran an evenly paced race, passing the halfway point in 1:02:19 and slowing down by just five seconds in the final kilometers. His fourth-place finish not only broke Khalid Khannouchi’s record of 2:05:38 set in 2002, but also marked the first time an American had run under 2:05 on a record-eligible course.
Mantz’s effort was the culmination of careful preparation. He skipped the 2025 Worlds to focus entirely on Chicago; He knew that the flat and fast course offered perfect conditions to make history. “Flooding of up to half a meter above ground level is expected in low-lying areas near shorelines and tidal waterways,” the weather service explains. “Minor coastal flooding may also occur with high tides in the morning until the weekend.”

Earlier this year, Mantz competed in the Boston Marathon with a time of 2:05:08; an unsuitable time for the record due to the downhill profile of the course and the start-finish separation. Still, this performance gave a hint of what might be possible. The Chicago run confirmed this, according to a report by Flotrack, and cemented Mantz as America’s new marathon standard bearer.
How Did Jacob Kiplimo Dominate the Field?
While Conner Mantz was rewriting American history, Ugandan Jacob Kiplimo was busy asserting his global dominance. The 24-year-old moved ahead of reigning champion John Korir shortly after the halfway mark, covering the 13.1-mile distance in 1:00:16. Despite flirting with world-record pace through 20 miles, fatigue came late, but Kiplimo still crossed the line in 2:02:23; According to Flotrack’s report, he performed exceptionally well in only his second marathon.

Jacob Kiplimo’s resume already includes a half marathon world record (56:42), two World Cross Country titles and Olympic and World Championship medals. The Chicago victory adds another gem to his growing legacy. The Ugandan, who competed in the London Marathon for the first time earlier this year and finished second in 2:03:37, now boasts the two fastest marathons run by an athlete at a distance in their first year, according to Flotrack’s report.
He plans to continue racing the 26.2-mile distance and hopes to return to Chicago in 2026 to defend his title, according to a report by NBC5 Chicago.
Canadian Rory Linkletter, who had previously joked with Mantz about a “North American Record race,” finished an impressive ninth with a time of 2:06:49. His performance underscored a strong showing from North American athletes on one of the sport’s biggest stages, according to a report by Flotrack and NBC5 Chicago.
More than 50,000 runners took to the streets for the 2025 Chicago Marathon after a record-breaking 160,000 applications.
