Emily Sisson, a two-time Olympian and World Championships finalist, seven-time national champion, and the American record holder in the marathon, will look to return to the United Airlines NYC Half podium after she finished second in both 2017 and 2018.

In November she made her TCS New York City Marathon debut, placing eighth as the third American. She also won the 2025 Boston 10K for Women, setting a new event record of 31:05.

The 34-year-old athlete finished as the runner-up at the 2024 U.S. Olympic Marathon Trials, securing her spot on Team USA. At the 2024 Paris Olympic Marathon she finished 23rd.

Sisson has a long history on track, making her Olympic debut in the 10,000 meters at the 2020 Tokyo Olympics. During the U.S. Olympic Trials, which saw unusually high temperatures, she set a new meet record and qualified for the Olympics, ultimately finishing 10th. She previously ran the 10,000 meters at the 2017 and 2019 World Athletics Championships, notching top-10 finishes in both.

2019 was a banner year for Sisson, as she came within five seconds of the American half marathon record in Houston, then clocked 2:23:08 at the London Marathon, at the time the fastest-ever debut by an American woman on a record-eligible course. She continued to dominate at the marathon distance and shattered the American record in 2022, running 2:18:29 in Chicago. Sisson followed up that performance with another American record in the half marathon in 2023 at the Houston Half Marathon, a time that was later eclipsed by Keira D’Amato and Weini Kelati.
