The 2026 Boston Marathon features a particularly fast and deep field of American marathoners. None is likely to win against the top international stars, including returning champions John Korir and Sharon Lokedi, but many look ready for fast efforts in what amounts to a preview of the 2028 U.S. Olympic Marathon Trials.
The top American women should challenge the American-in-Boston course record of 2:22:02 (2014), held by Shalane Flanagan. This group includes the entire USA 2024 Olympic team: Fiona O’Keeffe, Emily Sisson, and Dakotah Popehn, plus fourth-place Trials finisher Jess McClain.
In other words, these women are all recognized as first-rank talents.
That’s less true of a gaggle of U.S. men just a cut below established stars like Clayton Young, Zouhair Talbi, CJ Albertson, Galen Rupp, and Wesley Kiptoo. (Top American Conner Mantz has scratched due to injury and lack of training time.)
A surprising six of these relative unknowns have run under 2:10 in the last 16 months. Their performances have escaped the radar screen because they mostly ran in non-U.S. marathons and/or didn’t win despite their fast times.
Their names: Biya Simbassa, Ryan Ford, Daniel Mesfun, Alex Maier, Turner Wiley, and Haftu Knight. Here’s what you need to know about each of the six.
Biya Simbassa, 32
Marathon PR: 2:06:53; Valencia, Spain; Dec, 2024
Biya Simbassa has established himself as a consistent performer on the U.S. road scene, specializing in distances from 10K to the marathon. He has won five USATF road titles in recent years. His 2:06:53 in Valencia 16 months ago was, at the time, the fourth-fastest ever for an American (now fifth-fastest).
Quote: “The marathon’s about being in contention over the last 10K. That’s when it’s about what’s in your core. You have run all the strength, all the superficial fitness out of yourself, and it really comes down to what’s left inside you.”
Ryan Ford, 28
Marathon PR: 2:08:00; Boston; Apr, 2025
Ryan Ford is a rising star in American distance running who joined the On Athletics Club last year after ZAP Endurance closed. He had a standout collegiate career at Iowa State and the University of Tennessee at Martin. His 2:08 at Boston gained him 10th place in a major breakthrough performance. At the Houston Half Marathon in January, Ford improved his best at that distance to 59:48.
Quote: “In the marathon, you can’t be afraid to run with the best. If you want to be a 2:08 guy, you have to put yourself in a 2:08 position.”
Daniel Mesfun, 38
Marathon PR: 2:08:24; Seville, Spain; Feb, 2026
Born in Eritrea, Daniel Mesfun is a seasoned marathoner who now represents the United States, bringing with him a decade of international experience. He won the Dublin Marathon last October in a personal best of 2:08:51, and then improved this February again with a 2:08:24 in Seville. If he isn’t burned out from those two efforts, he could be a factor in Boston.
Quote: “The race starts at mile 20. Everything before that is just the commute to work. You have to be mentally ready to get going when your legs are telling you to stop.”
Alex Maier, 26
Marathon PR: 2:08:33; Dusseldorf, Germany; Apr, 2025
Alex Maier transitioned from a strong collegiate career at Oklahoma State to the professional ranks as a runner known for his massive aerobic engine. That showed clearly last year in Düsseldorf, just his second marathon, which followed hard on the heels of his American record for 10 miles (45:15). In January of this year, he ran 59:23 in the Houston Half Marathon.
Quote: “To compete at your best, especially as a distance runner, you need to be in the present. You have to learn to take it one lap at a time.”
Turner Wiley, 33
Marathon PR: 2:09:27; The Marathon Project (AZ); Dec, 2025
Turner Wiley is one of those “blue-collar” runners who is easy to root for. He has an undergraduate degree in human nutrition, works as a healthcare administrator at Seattle Children’s Hospital, and somehow manages to balance his job with 140-mile training weeks. Wiley was anything but a standout in college at Seattle Pacific University. His career has been defined by steady, incremental progress rather than overnight stardom.
Quote: “I’m just a regular guy who has put in years and years of work, and it finally paid off. If you keep working at it, the sky is the limit.”
Haftu Knight, 27
Marathon PB: 2:09:38; Chicago; Oct, 2025
Haftu Knight is an emerging distance talent whose journey from Ethiopia to the University of Texas has been defined by resilience and an independent racing style. He has run strongly on the track over 5,000 and 10,000 meters, and successfully moved up to the marathon last fall with his debut 26-miler in Chicago. Knight is known for his economical stride and mental toughness, and could become a next-generation leader on the American marathon scene.
Quote: “I’m the type of person who raises expectations on everything. I like to meet those expectations. If I said I could do this, I’m going to do this.”
There are several more American men running Boston with PRs in the 2:10-2:11 range, while the American women’s field also includes the likes of Sara Hall, Annie Frisbie, and Erika Kemp, all with bests of 2:22 or 2:23.
Any way you look at it, there have never been so many strong U.S. marathon runners in a Boston Marathon field. Perhaps they’ll sort themselves into pace groups through the early and mid miles.
But you can be sure the competition will heat up when they tackle Heartbreak Hill and race the final miles down Beacon Street to Kenmore Square before turning left on Boylston to view the massive blue-and-gold finish line 600 yards ahead. This is the race where each hopes to stake a claim in the future of American marathon running.
