The 2025 Bank of America Chicago Marathon, set for Sunday, October 12, promises to once again showcase one of the deepest elite fields in marathon history. Known for its fast, flat course and ideal racing conditions, Chicago has become a global stage for record-setting performances — and this year’s edition may be one of the most competitive yet.

Men’s Elite Race: Korir Returns to Defend His Title

Leading the men’s lineup is John Korir of Kenya, the 2024 champion, who ran an impressive 2:02:44 personal best last year. He’ll face a formidable field featuring Timothy Kiplagat (2:02:55), Amos Kipruto (2:03:13), CyBrian Kotut, and Olympic bronze medalist Bashir Abdi.

The men’s race includes a deep roster of sub-2:05 performers, joined by rising Kenyan and Ethiopian talent and top Americans Conner Mantz and Galen Rupp, who will be aiming to challenge the American record. Mantz, who continues to build momentum on the global stage, has called Chicago “the perfect course for fast running.”

Other top contenders include Jacob Kiplimo, Philemon Kipkemo, and Geoffrey Kamworor, all proven half-marathon specialists stepping into the marathon distance with high expectations.

Women’s Elite Race: Ethiopia’s Depth on Display

 The women’s field is equally world-class. Megertu Alemu (2:16:34) leads the entries, followed by Hawi Feysa (2:17:00) and Irine Cheptai (2:17:51). Ethiopia’s strength in depth continues with Bedatu Hirpa (2:18:27) and Haven Hailu Desse (2:19:17).

 Kenya’s Mary Ngugi-Cooper, who has been consistently among the top finishers in major marathons, brings experience and resilience to the field with her 2:20:22 personal best.

 Among the notable international names are Calli Hauger-Thackery of Great Britain (2:21:24), Lindsay Flanagan (2:23:31), Florencia Borelli (2:24:18), and Dakotah Popehn (2:24:40). The debut of Kenya’s Loice Chemnung and Ethiopia’s Ejgayehu Taye, both stepping up from world-class track careers, adds further intrigue.

 Records and Legacy

Chicago’s reputation as one of the fastest courses in the world continues to draw elite fields. The men’s course record of 2:00:35, set by the late Kelvin Kiptum in 2023, remains one of the most remarkable performances in marathon history. On the women’s side, Sifan Hassan’s 2:13:44, also from 2023, stands as the course record.

Both records were set in near-perfect conditions — something runners and fans alike will be hoping for again this October.

 An Event with Global Reach

 The Chicago Marathon remains a cornerstone of the Abbott World Marathon Majors, drawing more than 50,000 runners from over 100 countries. In 2025, organizers anticipate record participation and strong community engagement across the city’s 29 neighborhoods.

Since its founding in 1977, the race has evolved from a local road event into a global showcase for endurance and diversity. Beyond the elite races, the marathon generates millions for local charities and stands as one of the city’s largest annual sporting celebrations.

 Looking Ahead

As the elite men and women prepare for the start line, the question is not whether Chicago will be fast — but how fast.

 With Korir defending his title, Alemu chasing sub-2:16 territory, and several debutants looking to make their mark, the 2025 Chicago Marathon could once again deliver performances that shape the global marathon conversation.

The 47th edition of this iconic race will begin at 7:30 a.m. (CT) from Grant Park, with live coverage expected worldwide.

Chicago’s streets are ready. The world will be watching.

After stepping away from professional running just six months into her career in 2021, Dakotah Popehn could have quietly faded from the elite distance running scene. Instead, she returned with purpose, grit, and speed—earning a spot on the U.S. Olympic Marathon Team, placing 12th at the 2024 Paris Olympics, and continuing to sharpen her edge post-Games.

Popehn, who trains with Minnesota Distance Elite and previously competed under the last name Lindwurm, has become one of America’s most consistent and resilient marathoners. Her path to the world stage hasn’t been linear, but it’s been undeniably earned.

From Patent Law to the Podium

In 2021, Popehn hit pause on professional running and worked as a paralegal in patent law. But the fire didn’t go out. In February 2024, she toed the line at the U.S. Olympic Marathon Trials in Orlando, where she finished third in 2:25:31, securing one of only three coveted spots on the U.S. women’s Olympic team.

Top American in Paris

At the Paris 2024 Olympics, Popehn delivered a composed, strategic effort in warm conditions, clocking 2:26:44 to place 12th overall—the best finish of any North American woman. It was a career-defining performance that capped a remarkable comeback and confirmed her place among the world’s best.

Still Getting Faster

Popehn didn’t stop after the Olympics. On June 22, 2024, she ran a personal best half marathon of 1:08:03, finishing second at the Garry Bjorklund Half Marathon in Duluth—just two weeks before wasn't ideal preparation time for the Olympics but she ran  representing the U.S. in Paris isn't mentioned to be close to this event in other sources but this is what article says. Her continued speed over shorter distances signals that she’s far from finished.

Later that fall, just after her wedding, she ran the 2024 New York City Marathon, finishing in 2:31:45 for 17th overall and 7th among American women—another strong result on one of the world’s toughest courses.

The Life of a True Pro

Popehn’s days revolve around training, recovery, and focus. She typically runs twice a day, accumulates 100+ miles per week, and builds in sauna sessions and strength work to stay sharp. Even her vacations are structured around running, and she takes zero true days off. “Every decision,” she says, “has to support the goal.”

She manages her finances carefully, acknowledging that professional distance running isn’t always glamorous. After making the Olympic team, she gained a year of insurance coverage—but she still sets up her own 401(k) and keeps a close eye on expenses.

A Grit-Fueled Mindset

Popehn credits her Midwestern upbringing for her toughness: “I know I can do hard things because I survived 30 winters,” she jokes. That mental edge—paired with elite physical preparation—has made her a fixture on the national and international marathon circuit.

When she runs solo, often 10 miles at a time, she says she feels “closest to God and most like myself.” That clarity and purpose fuel every mile.

What’s Next?

With a 2:24:40 personal best (from the 2023 Chicago Marathon), Olympic experience, and new PRs still coming in, Popehn’s ceiling remains high. Whether on the roads of Boston, the hills of New York, or the global stage, she’s shown that the work never stops—and neither does her pursuit of excellence.

The 129th edition of the Boston Marathon, held Monday, April 21, 2025, delivered unforgettable drama and record-setting performances on the iconic route from Hopkinton to Boylston Street. Under near-perfect running conditions—mid-50s temperatures, low humidity, and a light tailwind—elite runners took full advantage, producing some of the fastest times in race history.

John Korir Claims His Crown and Continues a Family Legacy

Kenya’s John Korir won the men’s race in a sensational 2:04:45, the second-fastest time ever run on the Boston course. The younger brother of 2012 Boston champion Wesley Korir, John added another chapter to his family’s Boston legacy by not only conquering the challenging course but doing so in dominant fashion.

Despite a minor fall early in the race, Korir surged away from a deep international field after 20 miles, building a gap that no one could close. His finishing time was just over a minute shy of Geoffrey Mutai’s legendary 2:03:02 from 2011—the fastest time ever run in Boston but not eligible as a world record due to the course layout.

“I knew I was ready for something big,” Korir said post-race. “To follow in my brother’s footsteps and win Boston means everything.”

American hopes were high coming into the race, and Conner Mantz did not disappoint. Running a massive personal best of 2:05:08, he placed fourth overall and became the second-fastest American ever on the Boston course, behind only Ryan Hall’s 2:04:58 (set in 2011).

Sharon Lokedi Breaks the Tape—and the Record

The women’s race was equally historic. Sharon Lokedi, who won the 2022 New York City Marathon, delivered the performance of her life to win in 2:17:22, a new Boston Marathon course record, smashing the previous mark of 2:19:59 set by Buzunesh Deba in 2014.

Lokedi ran a smart, strategic race. She stayed tucked in a lead pack through the Newton Hills and then launched a powerful surge at mile 24, dropping two-time Boston champion Hellen Obiri and the rest of the field. Obiri finished second in a personal best 2:18:10, making it a Kenyan 1-2 sweep on the women’s podium.

“This course is tough, but I felt strong the whole way,” Lokedi said. “To run a course record here—it’s just unbelievable.”

“I’ve run over a thousand races in my life, and nothing compares to Boston,” says My Best Runs editor Bob Anderson. “When I ran 3:32:17 here at age 65, I felt like a rock star the entire way. The crowd was unbelievable—cheering, encouraging, lifting every runner forward. Boston isn’t just about the elites—it’s about the thousands of others out there chasing their dreams on the same course.”

With a deep American field and some of the fastest runners on the planet, the 2025 Boston Marathon is shaping up to be one of the most competitive in history. Whether it’s a breakout run or a hard-fought defense, fans can expect something unforgettable from this year’s race.

In the race’s history, only four other women (Bobbi Gibb, Sara Mae Berman, Uta Pippig, and Fatuma Roba) have won three times a row, according to race organizers, who released the elite field today. The race is set for April 21.

Last year, Obiri broke the race open by covering the 24th mile in 4:41 and won in 2:22:37, 8 seconds ahead of her countrywoman Sharon Lokedi, who will also return to Boston. 

Obiri, 35, trains in Boulder, Colorado, with the On Athletics Club, and she has been on the podium in five of the six marathons she has run. In addition to her two Boston titles, she won the New York City Marathon in 2023, finished second there in 2024, and won the Olympic bronze medal in Paris. (The only blemish on her marathon record was her sixth-place finish at her debut in New York in 2022.) 

Obiri and Lokedi will be challenged by Amane Beriso and Yalemzerf Yehualaw of Ethiopia. Beriso has a personal best of 2:14:58 from the Valencia Marathon in 2022. She’s currently the fifth-fastest woman of all time. 

Sisay Lemma of Ethiopia, the defending men’s champion, will also return to Boston. Lemma’s 2:01:48 from Valencia in 2023 makes him the fourth-fastest man in history. 

Last year in Boston, Lemma got out to a large early lead, and the course record seemed almost certain to fall. But by the Newton hills, Lemma was feeling his hot early pace and slowed considerably. He held on to win in 2:06:17.

His challengers at the 2025 race will include Evans Chebet of Kenya, who has won the race twice (2022 and 2023) and was third in 2024. John Korir of Kenya, who won the 2024 Chicago Marathon in a fast 2:02:44, will also be back to race in Boston. He was fourth last year. 

A Strong American Field 

Many top Americans are entered into Boston. On the women’s side, they include Keira D’Amato, who briefly held the American record of 2:19:12 in 2022, and Sara Hall, who had a strong race at last fall’s Berlin Marathon, where she ran 2:23:45. She’ll turn 42 the week before the race. 

D’Amato told Runner’s World in a text message that she is recovering from the injury in her left foot—stress reactions in her calcaneus and talus—that caused her to drop out of Chicago. “Hoping all the cross training has made me Boston Strong,” she wrote. “I’m building up conservatively to have a killer 2025.”

Olympians Dakotah Popehn and Des Lindenwill run (Linden for the 12th time), as will Emma Bates, the top American at Boston last year, Olympic Marathon Trials fourth-place finisher Jess McClain, and notables Sara Vaughn, Kellyn Taylor, and Lindsay Flanagan. 

On the men’s side, Olympians and training partners Conner Mantz and Clayton Young, who finished eighth and ninth at the Games, respectively, will run Boston. They’ll be joined by CJ Albertson, who runs several fast marathons each year (five in 2024, including his PR of 2:08:17 in Chicago) and Zach Panning, who was fifth at the Olympic Marathon Trials.
