Who to watch at Boston

Boston is the marathon where a 2:03 runner can get beaten by a 2:08 grinder, because the course punishes bad timing more than raw speed. The 130th edition is on Monday, April 20, and the men’s field includes 25 runners who have already broken 2 hours 7 minutes somewhere else. (baa.org) The first name to know is John Korir of Kenya, because he is the defending champion and eight of last year’s top 10 men are coming back to chase him. Boston also gets Benson Kipruto back for the first time since 2023, and he already owns wins in Boston in 2021, Chicago in 2022, Tokyo in 2024, and New York City in 2025. (baa.org) If you want the American angle, start with Galen Rupp, because he is 39 years old, a four-time Olympian, and still the biggest U.S. name in the field. Team USA lists him as a two-time Olympic medalist, and World Athletics lists his age at 39 going into this race. (teamusa.com) (worldathletics.org) Rupp is not just a famous veteran who showed up for nostalgia. His marathon best is 2:06:07, and the Boston Athletic Association says he is one of the Americans racing for the podium on Patriots’ Day. (sixminutemile.com) (baa.org) Rory Linkletter is the other easy name to latch onto, because he turned himself from cult favorite into real contender with a 2:06:49 personal best at the 2025 Chicago Marathon. The Boston Athletic Association also notes he was sixth in Boston last year in 2:07:02, which matters here because Boston rewards runners who already know where the hills bite. (worldathletics.org) (baa.org) Ryan Ford is the quieter name, but he may be the most interesting U.S. climber in the race. Boston’s organizers list him as last year’s 10th-place finisher, and On says that same 2025 race was his breakout, when he ran 2:08:00 against a front pack stacked with international stars. (baa.org) (press.on-running.com) There is also a reason previews keep circling back to Zouhair Talbi and Conner Mantz when people talk about the American side. Six Minute Mile says Talbi’s 2:05:45 makes him the No. 3 man on the all-time U.S. list, and the Boston Athletic Association had already flagged Mantz as part of the domestic group before adding more names in January. (sixminutemile.com) (baa.org) The women’s race is just as loaded, and the easiest entry point is Sharon Lokedi. She won Boston in 2025 in a course record 2:17:22, and this year’s field also includes Emily Sisson, Fiona O’Keeffe, and Dakotah Popehn from the full 2024 U.S. Olympic Marathon team. (sixminutemile.com) (baa.org) One wrinkle before race day is that the field is still moving. On April 3, the Boston Athletic Association said Milkesa Mengesha and Ser-Od Bat-Ochir had been added to the men’s field, while Keira D’Amato and Biya Simbassa were among the withdrawals. (baa.org) So if you are watching Boston for the first time, the cleanest map is this: Korir and Kipruto are the proven champions, Rupp is the decorated veteran, Linkletter is the form pick rising into the top tier, and Ford is the returning top-10 American trying to turn one breakout into two. That is why a race with 32,494 entrants can still come down to a handful of names before the pack even reaches the Newton hills. (baa.org) (sixminutemile.com)
