America's fastest records-legal marathon was on tap this Sunday as domestic and international challengers including Conner Mantz, Jacob Kiplimo, and Ejgayehu Taye sought to set PBs, break records, and make podiums at the 2025 Bank of America Chicago Marathon.

Mantz had been on a roll since his 8th-place Olympic marathon finish, placing 6th at New York, breaking Ryan Hall's U.S. half marathon record twice, and most impressively running 2:05:08 for 4th place at the 2025 Boston Marathon. The point-to-point nature of Boston's course makes it susceptible to wind assistance and ineligible for records, but the Windy City (despite its nickname) doesn't have that problem as its marathon course is flat, fast, and loop-based. As Khalid Khannouchi's 2:05:38 American record turned 23 years old, the question was whether Mantz could pair his half-marathon record with the full NR and whether he could podium while doing it.

The battle for the men's win was expected to be between Kenya's defending champ John Korir and the Ugandan sensation Jacob Kiplimo, who holds the half-marathon world record at 56:42. Korir was coming off a win at the Boston Marathon, while Kiplimo was running the second marathon of his life (his first was a solid 2:03:37 for runner-up in London). Canadian Rory Linkletter was aiming for top North American honors -- he had said he would be targeting Cam Levins' North American marathon record of 2:05:36.

There were a host of other Americans. Rio Olympic marathon bronze medalist Galen Rupp toed the line, though at 39 years old he had struggled mightily since 2021. Ryan Ford at 2:08:00 in Boston this year came in with a fast seed time, while CJ Albertson was coming off a 40th-place Worlds finish. BYU teammates Casey Clinger and Creed Thompson were making their debuts at the marathon distance. And lastly, 2016 Olympic champ Matt Centrowitz was running his second marathon -- his PB was 2:24 set while pacing the race last year.

On the women's side, Valencia Marathon champ Megertu Alemu of Ethiopia led the seeds although many were anticipating the debut of her countrywoman Ejgayehu Taye, who holds impressive 14:12 (5K) and 64:14 (half marathon) PBs and swept the Kingston Grand Slam Track distance races earlier this year. It should be noted that a gloomy cloud of suspicion engulfed this year's event, given that last year's champion and world record-setter Ruth Chepngetich was suspended for violating anti-doping rules months after her race and thus won't be returning.

Paris Olympian Dakotah Popehn (formerly Lindwurm) was looking for a big PB to lead the U.S. women in Chicago. She was expected to face 8th-place Trials finisher Lindsay Flanagan and Natosha Rogers, who had a rough Trials debut but improved to 7th at this year's Nagoya Marathon. Continuing the trend of BYU athletes excelling on the roads was Aubrey Frentheway, coming off a surprise U.S. 20K championships victory. '23 NCAA 10K runner-up Emily Venters was making her debut.

10:57 A.M. ET - Feysa extends her lead, sets massive PB to win 2025 Chicago; Natosha Rogers top American in 6th

Feysa has skipped the 2:16s and the 2:15s, going from 2:17:00 to 2:14:56 to win the 2025 Chicago Marathon women's race. Her last mile was the fastest of the race, giving her a sizeable lead over pre-race favorite Megertu Alemu.

Feysa said in Amharic after the race that she wanted to thank God and the organizers for inviting her to the race. She also thanked her coach for giving her morale to know that she could win the race.

Natosha Rogers upset Paris Olympian Dakota Popehn to take top American honors, finishing in 2:23:28. Rogers said after the race that the marathon experience came in waves, with good waves and bad waves often coming back to back. She congratulated Mantz on his American record.

10:35 A.M. ET - Jacob Kiplimo wins 2025 Chicago Marathon, Mantz sets American record in 4th

It was far from an easy race, but the half marathon talent has proven he can do it over the full. After a blistering 2:00 marathon pace through 21 miles, Jacob Kiplimo PRs by over a minute, finishing in 2:02:23. The sky is the limit for Kiplimo going forward, as he was able to beat a stacked field by over a minute. Amos Kipruto finishes 2nd in 2:03:54.

Behind him, Mantz sets a new American record in 2:04:43. This moment has been 23 years coming, and Mantz has been able to do what marathon greats like Galen Rupp haven't in breaking Khalid Khannouchi's 2:05:38 mark. In a show of class, Khannouchi is on site to congratulate Mantz on breaking his record.

Speaking in an interview, Kiplimo said at the end he was just thinking of his personal best as the world record slipped away. He said he hoped to run more marathons in the future.

10:26 A.M. ET - Kiplimo on 2:01:30 pace now

Even at his slowing 2:01:30 predicted finish, Kiplimo is about to write his name into the history books as one of the fastest marathoners in history. He holds a 90-second lead over Kipruto. He's hurting, no doubt -- Kiplimo just split a 5:05 mile, the slowest of the race.

Feysa and Alemu are the only two women who could win this race 35K in -- Feysa's 11-second gap isn't yet insurmountable. She's managed to hold onto a steady 2:15 flat tempo. Natosha Rogers has built a lead over Popehn for top American honors on a 2:22 tempo.

10:17 A.M. ET - Pace slows as Kiplimo secures his winning position

The legacy of Kelvin Kiptum remains unbeaten for now, as Kiplimo's predicted finish slows to 2:00:47 at 23 miles. Despite that, his lead over Kipruto has only grown to over a minute and 20 seconds. Mantz is on 2:04:42 pace running just behind Alex Masai, on pace for a historic U.S. marathon record.

10:14 A.M. ET - Can Kiplimo hold on to the world record?

Kiplimo's lead is still commanding, but the marathon world record is only barely hanging on with a predicted finish of 2:00:30 at 35K. Can the track runner pull out a kick to keep the historic pace alive?

In the men's race at 20 miles, Kiplimo is running against the clock. The 2:00:13 pace is hard to believe, but it's true: Kiplimo may just be your new marathon world record holder with the 2-hour barrier still on the table.

Incredibly, Korir and Kiplimo are picking up the pace. Their 2:00:30 former predicted finish is now 2:00:10 at 25K! They've built a ten-second lead over Kipruto -- now 27 seconds past the split. That was an incredible burst of pace this late in the race, as the world record is officially on notice. Mantz is on 2:04:20 pace in the chase pack as they'll try to reel in Kimaiyo and Kiplagat who have fallen off the lead pack.

Shari and Feysa made a break early, but they may be paying for it already as Ethiopians Megertu Alemu and Ejgayehu Taye, the pre-race expected favorites, are just seven seconds behind at the half. Their 1:07:30 is spot-on for 2:15:00 full marathon pace.

9:28 A.M. ET - The Big Five lead pack still on world record pace

Viewers should savor that 2:00:32 predicted finish time on the live splits however long it lasts. The five Kenyans of Kiplimo, Korir, Kipruto, Kimaiyo, and Kiplagat, aside from their names rolling off the tongue, are running beautifully at 57:06 through 20K despite a slight slowing. Kiplagat is the only one showing signs of weakness falling four seconds behind the pack. After the half split, Korir is pulling past the pacers and seems to be making a lead for himself for the first time now.

The chase pack of 11 is still running strong, with Mantz still firmly in it on 2:04:38 pace.

8:30 A.M. ET - Elite men's and women's races start

The elites are out with a clean start! The top men's group is going at about 60:30 pace through the half as scheduled. It's a 4:25 first mile for the men,, but that speed is a little misleading as there's a significant tailwind.

The women are being paced for a 67 flat half marathon, about 2:14 full marathon pace.

8:20 A.M. ET - Wheelchair races begin

The morning will kick off with the men's wheelchair start at 8:20 and the women's one minute later. Switzerland's Marcel Hug has won the last four World Marathon Majors and will be a heavy men's favorite, though sadly last year's runner-up Daniel Romanchuk is out with injury due to colliding with a spectator at the Sydney Maratthon. This year's American Boston and Sydney champ Susannah Scaroni leads the women's field, but a U.S. victory won't be certain: 2025 Tokyo and London winner Catherine Debrunner could challenge as well as her Swiss countrywoman Manuela Schar, who is coming off a win at Berlin.

The races are off!
