A field of 9,000 participants – including world-class professional athletes, Boston Marathon champions, and American record holders – will compete in New England’s signature half marathon

BOSTON – The 2023 B.A.A. Half Marathon presented by Dana-Farber Cancer Institute and the Jimmy Fund will be held this Sunday, November 12, starting and finishing within Boston’s Franklin Park. A field of 9,000 athletes from Greater Boston and beyond will take to the roads of Boston and Brookline in pursuit of the coveted unicorn finisher’s medal.

The B.A.A. Half Marathon will start at 8:00 a.m. this Sunday, November 12, from Franklin Park. The 13.1-mile course runs along the picturesque Emerald Necklace Park System, past area landmarks such as the Arnold Arboretum and Franklin Park Zoo, before finishing at White Stadium in Franklin Park. A detailed course map can be found here.

Dana-Farber Cancer Institute and the Jimmy Fund have partnered with the B.A.A. Half Marathon since 2003 as the race’s presenting sponsor and exclusive charity team. Through this relationship, Dana-Farber runners have collectively raised more than $8.6 million to support groundbreaking cancer research at Dana-Farber Cancer Institute, and enabled Dana-Farber scientists and clinicians to positively impact the lives of cancer patients around the world. A team of 600+ athletes will be part of the Dana-Farber Cancer Institute and the Jimmy Fund’s team for this year’s event, having already raised over $630,000 to defy cancer. Those interested in supporting Dana-Farber’s team can make a donation here.

At the front of the field, Boston Marathon champions and American record holders will vie for top honors. Among the notable professional athletes entered are defending open division champions Geoffrey Koech and Viola Chepngeno; wheelchair winner and course record holder Jenna Fesemyer; as well as Para Athletics Division champions Marko Cheseto and Liz Willis.

American half marathon record holder and 2022 B.A.A. 10K champion Keira D’Amato returns to the Bay State for her first B.A.A. Half Marathon. She’ll be joined by fellow Team USA members from this year’s World Athletics Championships Natosha Rodgers and Lindsay Flanagan.

A total of eleven men have personal bests under 1:01:00, while 15 women have run 1:10:00 or faster for the half marathon distance. The complete professional field can be found here, while professional athlete bios are available here.

Of note, previously announced competitors Lelisa Desisa (two-time champion), last year’s runner-up Bosena Mulati, and American marathoner Susanna Sullivan have withdrawn. Any additional field updates will be incorporated in the above professional field link.
